Description

  Embodiments described herein relate generally to an interpretation report system.

  In the medical field, specialized fields are subdivided. For example, when interpreting a medical image representing a plurality of cross-sectional images of a subject acquired by a medical image diagnostic apparatus such as an X-ray CT apparatus, an MRI apparatus, or an ultrasonic diagnostic apparatus, request a specialized doctor (interpretation doctor). It is widely done. The interpreting doctor performs a task of collecting the findings as an interpretation report while confirming the medical image to be interpreted.

  For example, an interpretation report creation apparatus is used to create the interpretation report. In the interpretation report creation using the interpretation report creation apparatus, the interpretation doctor confirms the medical image displayed on the display unit and finds the findings. The interpretation is performed by the interpretation doctor inputting the findings. The medical image used for finding the finding may be referred to as a “key image”.

  When creating an interpretation report, the interpretation doctor may paste the key image into a desired image reference field of the interpretation report. As an example of a pasting operation when a key image is pasted, the image interpretation doctor selects a desired key image via the operation unit or the like and performs a drag operation on the key image. Then, the image interpretation doctor drops the dragged key image in a desired image reference field (drag and drop operation). By the pasting operation, the medical image data representing the key image and the image reference field are linked.

  For example, when pasting a key image on an interpretation report, the interpreting physician may want to paste a medical image at a cross-sectional position before and after the cross-sectional position of the key image on the interpretation report. In this case, the image interpretation doctor performs the pasting operation on the medical images at the front and rear cross-sectional positions separately from the pasting operation on the key image.

  In addition, the interpretation doctor may want to paste a medical image acquired in the past rather than the key image into the interpretation report. In this case, the interpreting physician has performed pasting operations on medical images acquired in the past, separately from pasting operations on key images. In this way, there are cases where the interpretation report creation work becomes complicated.

  When a doctor requesting an interpretation report refers to an interpretation report, he or she may want to refer to medical images at cross-sectional positions before and after the key image and medical images acquired in the past. However, as described above, the medical image at the cross-sectional position before and after the key image or the past is acquired due to the complexity of pasting the medical image at the cross-sectional position before and after the key image or the medical image acquired in the past. Medical images may not be pasted enough. In this case, the requesting doctor reads and refers to the medical image at the cross-sectional position before and after the key image and the medical image acquired in the past from the medical image storage device using the image viewer.

  When the image viewer is not installed in the reference terminal, the reference terminal cannot refer to the medical images at the cross-sectional positions before and after the key image and the medical images acquired in the past. Therefore, for example, an interpreting doctor may be forced to perform operations such as searching for a reference terminal in which an image viewer is installed and searching for past interpretation reports. As described above, when the requesting doctor refers to the interpretation report, the medical images at the cross-sectional positions before and after the key image and the medical images acquired in the past may not be easily seen.

<First Embodiment>
(overall structure)
FIG. 1 is a block diagram showing a configuration of an image interpretation report system according to the first embodiment. The interpretation report system according to the first embodiment includes, for example, a medical image diagnostic apparatus 1, a medical image storage apparatus 2, an interpretation report creation apparatus 3, an interpretation report storage apparatus 4, and an interpretation report reference apparatus 5. Consists of. These devices are communicably connected via a network N such as a LAN (Local Area Network). Communication between apparatuses preferably conforms to DICOM (Digital Imaging and Communications in Medicine), which is a standard for medical images, but other standards may be applied as appropriate. Information communication is industry standard TCP / IP (Transmission Control Protocol / Internet Protocol) communication, and data is exchanged in packets via the network N.

  As the medical image diagnostic apparatus 1, for example, an X-ray CT (Computed Tomography) apparatus, an MRI (Magnetic Resonance Imaging) apparatus, an ultrasonic diagnostic apparatus, or the like is applied. These medical image diagnostic apparatuses 1 may be called modalities. The medical image diagnostic apparatus 1 acquires a plurality of cross-sectional image data of a subject. A plurality of cross-sectional image data is collected in a direction perpendicular to the cross-section. A predetermined coordinate system is set for the collected cross-sectional image data. As an example, the acquired plurality of cross-sectional image data is transmitted to the medical image storage device 2 in a file format compliant with DICOM. Note that there is a one-to-one correspondence between images and image data. Therefore, in the present specification, these may be identified.

  Accompanying information is attached to each cross-sectional image data. For example, the incidental information includes an image UID that identifies the cross-sectional image data, a subject ID that can identify the subject, date and time information that indicates the date and time when the cross-sectional image data was acquired, modality type information that represents the type of modality, It is set to site information representing the site of the subject from which cross-sectional image data was acquired, cross-sectional direction information representing the cross-sectional direction of the cross-sectional image data, slice thickness information representing the slice thickness of the cross-sectional image data, and a plurality of cross-sectional image data Coordinate system information representing a coordinate system and slice position information representing a slice position (cross-section position) of the cross-sectional image data.

  The medical image storage device 2 is a computer that constitutes a medical image database. The medical image storage device 2 includes an image data storage unit 21. The image data storage unit 21 receives a plurality of cross-sectional image data of the subject from the medical image diagnostic apparatus 1 and stores the cross-sectional image data in advance.

  The interpretation report creation apparatus 3 is an apparatus for creating an interpretation report based on an instruction input by an operator such as an interpretation doctor. Details of the interpretation report creation apparatus 3 will be described later.

  The interpretation report storage device 4 is a so-called database. The interpretation report storage device 4 includes an interpretation report data storage unit 41. The interpretation report data storage unit 41 stores interpretation report data created by the interpretation report creation device 3. The interpretation report data storage unit 41 stores a template for a creation screen for creating an interpretation report and a key image pasted on the interpretation report data. The interpretation report creation device 3 and the interpretation report storage device 4 may be configured as hardware as a single device.

  The interpretation report reference device 5 is a so-called computer, and is a reference terminal for an operator such as a requesting doctor to refer to the interpretation report.

(Configuration of interpretation report creation device 3)
FIG. 2 is a block diagram showing the configuration of the interpretation report creation apparatus 3. The interpretation report creating apparatus 3 includes an operation unit 31, a display unit 32, a distance information storage unit 33, a front and rear image data specifying unit 34, an attachment unit 35, and a display control unit 36.

  The operation unit 31 is an operation device for an operator to input various instructions to the interpretation report creation apparatus 3. The operation unit 31 includes an operation device such as a keyboard, a mouse, a trackball, and a joystick. Further, as the operation unit 31, a touch panel based on a GUI (Graphical User Interface) displayed on the display unit 32 may be used.

  The display unit 32 is a display device that displays an interpretation report and a cross-sectional image. The display unit 32 is configured by a display device such as a liquid crystal display or an organic EL (Electroluminescence) display.

  The distance information storage unit 33 stores in advance distance information representing the distance in the slice thickness direction of the slice image data. FIG. 3A is a table showing an outline of an example of distance information. For example, the distance information storage unit 33 stores distance information for each modality type and each part of the subject. The distance represented by the distance information is a length for determining the capturing range of the preceding and following image data attached to the interpretation report data in conjunction with the key image attachment instruction (details will be described later). In the example of FIG. 3A, the modality type “CT” indicates an X-ray CT apparatus, the modality type “MR” indicates MRI, and the modality type “US (B mode)” indicates a B mode ( Brightness Mode).

  In the example of FIG. 3A, the distance “30 mm” is associated with the pair of the modality type “CT” and the subject part “head”, and the distance “30” is associated with the pair of the modality type “CT” and the subject part “chest”. 50 mm ”is associated, the distance“ 65 mm ”is associated with the pair of the modality type“ MR ”and the part“ abdomen ”of the subject, the modality type“ US (B mode) ”and the part“ abdomen ”of the subject. A distance “20 mm” is associated with the pair.

  Further, the distance information storage unit 33 may further store distance information for each cross-sectional direction of the key image data. FIG. 3B is a table showing an outline of an example of distance information. In the example of FIG. 3B, the distance “30 mm” is associated with the combination of the modality type “CT”, the subject part “head”, and the cross-sectional direction “axial”, and the modality type “CT” and the subject part “ The distance “40 mm” is associated with the combination of the “head” and the cross-sectional direction “sagittal”, and the distance “60 mm” is associated with the combination of the modality type “MR”, the part “abdomen” of the subject, and the cross-sectional direction “axial”. The distance “65 mm” is associated with the combination of the modality type “MR”, the part “abdomen” of the subject, and the cross-sectional direction “coronal”.

  Each distance information is input in advance to the distance information storage unit 33 by a medical staff such as an interpretation doctor. For example, each of the distance information is input with a distance that is assumed to be often referred to during interpretation. The distance that is assumed to be often referred to during interpretation is determined clinically, for example, by the size of a lesion (such as a tumor) that is likely to occur in the region, the spatial resolution in each cross-sectional direction of the modality, etc. Entered.

  The front and rear image data specifying unit 34 is based on the distance represented by the distance information, the slice thickness, and the slice position of the designated key image data, and is included in the range represented by the slice position and the distance. Identify the data. For example, when the operator designates a key image via the operation unit 31 and gives an attachment instruction for attaching the key image to the interpretation report, the front and rear image data specifying unit 34 reads the cross-sectional image data of the designated key image. In response to the image UID of the key image data, the slice position information included in the accompanying information of the key image data is read. Thereby, the front and rear image data specifying unit 34 specifies the slice position of the key image data.

  The front-rear image data specifying unit 34 specifies the distance represented by the modality type and the distance information stored for the part. For example, the front and rear image data specifying unit 34 receives the image UID of the key image data and specifies the key image data from the cross-sectional image data stored in the image data storage unit 21. The front and rear image data specifying unit 34 reads the modality type information and the part information included in the incidental information of the specified key image data. As a result, the front and rear image data specifying unit 34 specifies the modality type of the key image data and the part of the subject.

  The front-rear image data specifying unit 34 searches for distance information (see FIG. 3A) associated with the specified modality type and subject part pair from the distance information stored in the distance information storage unit 33. Thus, the distance represented in the distance information stored for the modality type and the part is specified. For example, when the specified modality type is “CT” and the specified part of the subject is “head”, the front and rear image data specifying unit 34 specifies the distance as “30 mm”.

  The front and rear image data specifying unit 34 may specify the distance represented by the distance information stored for the modality type, the part, and the cross-sectional direction. At this time, for example, the front and rear image data specifying unit 34 receives the image UID of the key image data and specifies the key image data from the cross-sectional image data stored in the medical image storage device 2. The front and rear image data specifying unit 34 reads the modality type, the part information, and the cross-sectional direction information included in the incidental information of the specified key image data. Thereby, the front and rear image data specifying unit 34 specifies the modality type, the part of the subject, and the cross-sectional direction of the key image data.

  The front-rear image data specifying unit 34 stores distance information (see FIG. 3B) associated with the combination of the specified modality type, the region of the subject and the cross-sectional direction, among the distance information stored in the distance information storage unit 33. Is used to specify the distance represented in the distance information stored for the modality type, the part, and the cross-sectional direction. For example, when the specified modality type is “CT”, the specified region of the subject is “head”, and the specified cross-sectional direction is “axial”, the preceding and following image data specifying unit 34 The distance is specified as “30 mm”.

  The front-rear image data specifying unit 34 specifies a range represented by the specified distance and slice thickness. For example, the front and rear image data specifying unit 34 reads the coordinate system information attached to the key image data, and specifies the coordinate system set for the plurality of cross-sectional image data including the key image data. The front and rear image data specifying unit 34 specifies the slice position of the key image data by reading the slice position information attached to the key image data. The front and rear image data specifying unit 34 specifies the slice thickness of the key image data by reading the slice thickness information attached to the key image data.

  The front and rear image data specifying unit 34 specifies a range included in the specified distance with respect to the front direction and the rear direction perpendicular to the cross section from the specified slice position in the specified coordinate system. These anteroposterior relationships are defined in the specified coordinate system. Further, the front and rear image data specifying unit 34 calculates the number of data of the cross-sectional image data included in the specified range based on the specified distance and the specified slice thickness. The front-rear image data specifying unit 34 calculates the number of pieces of cross-sectional image data included in the specified range by dividing the specified distance by the specified slice thickness. For example, when the specified distance is “30 mm” and the specified slice thickness is “6 mm”, the front and rear image data specifying unit 34 calculates the number of data as “5”.

  The front and rear image data specifying unit 34 specifies the front and rear image data by extracting cross-sectional image data corresponding to the calculated number of data. For example, when the calculated number of data is “5”, the front-rear image data specifying unit 34 includes five pieces of cross-sectional image data and key image data in the forward direction perpendicular to the cross-section from the slice position of the key image data. 5 pieces of cross-sectional image data are extracted from a plurality of cross-sectional image data including the key image in the backward direction perpendicular to the cross-section from the slice position. At this time, the front-rear image data specifying unit 34 refers to slice position information attached to each cross-sectional image data among the plurality of cross-sectional image data including the key image, and the cross-sectional image data corresponding to the calculated number of data. Is specified as the front and rear image data. The front and rear image data specifying unit 34 outputs the specified image UID of the front and rear image data and the image UID of the key image data to the attachment unit 35.

  Although the example in which the front and rear image data specifying unit 34 extracts the cross-sectional image data in both the front direction and the rear direction has been described here, the present invention is not limited to this. The front and rear image data specifying unit 34 may extract cross-sectional image data only in the front direction or only in the rear direction.

  The attachment unit 35 attaches the preceding and following image data together with the key image data to the interpretation report data. FIG. 4 is a conceptual diagram showing processing by the attachment unit 35. For example, when an image interpretation report is created, by a drag-and-drop operation, the image interpretation doctor designates a desired image as a key image among the cross-sectional images displayed on the image viewer screen W1, and the desired image reference field R1 ( An attachment instruction to the interpretation report creation screen W2) is performed. Based on the UID of the front and rear image data G2 and the image UID of the key image data G1 from the front and rear image data specifying unit 34, the attachment unit 35 selects key image data from the cross-sectional image data stored in the image data storage unit 21. G1 and front and rear image data G2 are specified. The attachment unit 35 attaches the specified key image data G1 and the preceding and following image data G2 to the interpretation report data in association with the image reference field R1 related to the attachment instruction. The position of the image reference column R1 is designed as appropriate. In addition, when there are many image data (G1, G2) to be attached or when the image data size is large, it may take time to paste. In this case, the attachment unit 35 performs attachment processing in the background. May be.

  The attachment unit 35 displays the attached information representing the information of the image UID and slice position of the attached key image data G1, the image UID and slice position of the preceding and following image data G2, and the associated image reference field R1. Output to.

  The attachment unit 35 interprets the key image data G1 and the preceding and following image data G2 so that the image group including the key image data G1 and the preceding and following image data G2 can be turned and displayed every time a predetermined image turning instruction is received. Attach to data. Examples of the image turning instruction include a mouse wheel operation as the operation unit 31 and a touch panel swipe operation as the operation unit 31. In the case of this example, each image in the image group attached to the interpretation report data is displayed in turn according to the slice position in accordance with the wheel operation.

  Each time the display control unit 36 receives a predetermined image turning instruction based on the attachment information from the attachment unit 35, the display control unit 36 sets the image group including the key image data G1 and the preceding and following image data G2 in the image reference field of the interpretation report. The key image and the front and rear images are flipped and displayed. An example of the image turning instruction is a mouse wheel operation as the operation unit 31. For example, the display control unit 36 flips and displays each image of the image group attached to the interpretation report data in the order of slice positions according to the wheel operation. The turn display order is determined based on the image UID and slice position of the key image data included in the attached information, the image UID and slice position of the preceding and following image data G2, and the information in the associated image reference column R1.

  The display control unit 36 may display a slider indicating the slice position of the image displayed in the forefront of the image group. FIG. 5 is a schematic diagram illustrating a display example of key images and front and rear images in an interpretation report. For example, the display control unit 36 displays the reference window W3 on the display unit 32 in response to an operation instruction such as double-clicking on the image reference field. The display control unit 36 displays the slider SL1 and the movement axis A1 to which the slider SL1 can move in the vicinity of the displayed image. The aspects of the slider SL1 and the movement axis A1 are appropriately designed. In the example of FIG. 5, “0” on the movement axis A1 represents the slice position of the key image. “+” And “−” on the movement axis A1 represent the forward direction and the backward direction with respect to the slice position, respectively. The display control unit 36 displays the slider SL1 at a position on the movement axis A1 corresponding to the slice position of the image displayed on the foreground. The display control unit 36 may display the slider SL1 and the movement axis A1 in the vicinity of the image reference field R1 on the interpretation report creation screen.

  The display control unit 36 receives an instruction to move the slider SL1 as an image turning instruction, and turns and displays the image group. For example, an operator such as an interpreting doctor or a requesting doctor performs a drag operation for moving the slider SL1 along the movement axis A1 using the operation unit 31 such as a mouse. The display control unit 36 receives this drag operation as an image turning instruction and turns and displays the image group. At this time, the display control unit 36 refers to the image UID and slice position of the key image included in the attached information, the image UID and slice position of the preceding and following image data G2, and moves the slider SL1 to the position on the movement axis A1. In conjunction with this, the image to be displayed on the foreground is switched and displayed.

  The display control unit 36 may display the image of the key image data G1 (key image) and the image of the front and rear image data G2 (front and back images) in a display mode that can be identified. A specific display mode is appropriately designed. For example, the display control unit 36 changes the line thickness and color of the display frame of the image when displaying the key image on the foreground and when displaying the preceding and following images on the foreground.

  Further, the display control unit 36 may display text information indicating the type of the image displayed in the foreground in the vicinity of the image. For example, when the key image is displayed on the forefront, the display control unit 36 displays text information “key image” in the vicinity of the key image. When the front and rear images are displayed on the foreground, the display control unit 36 displays text information “front and rear images” in the vicinity of the front and rear images.

  The display control unit 36 identifies the type of the image displayed in the foreground while referring to the image UID and slice position of the key image included in the attached information, and the image UID and slice position of the front and rear image data G2, and displays the image type. Make changes.

  In addition, each image of the attached image group is not limited to the form displayed in a flipped manner. For example, the images in the attached image group may be displayed side by side in a predetermined layout.

  In this manner, the preceding and following image data G2 is attached to the interpretation report in conjunction with the attachment instruction for attaching the key image data G1. As a result, when the requesting doctor or the like refers to the interpretation report, or when the interpretation doctor refers to the interpretation report being created, the requesting doctor or the interpretation doctor simply refers to the cross-sectional image close to the slice position of the key image. be able to.

  FIG. 6 is a flowchart showing an operation in which the interpretation report system according to the first embodiment attaches the key image data G1 and the front and rear image data G2 to the interpretation report data.

  Step S101: The preceding and following image data specifying unit 34 receives an attachment instruction for attaching a key image to an interpretation report. At this time, the preceding and following image data specifying unit 34 receives the image UID of the key image data G1 which is the cross-sectional image data of the designated key image, and reads the slice position information included in the incidental information of the key image data G1. Thereby, the front and rear image data specifying unit 34 specifies the slice position of the key image data G1.

  Step S102: The front and rear image data specifying unit 34 receives the image UID of the key image data G1, and specifies the key image data G1 from the cross-sectional image data stored in the medical image storage device 2. The front and rear image data specifying unit 34 reads the modality type information and the part information included in the incidental information of the specified key image data G1. Thereby, the back and forth image data specifying unit 34 specifies the modality type and the part of the subject of the key image data G1. The front and rear image data specifying unit 34 may further specify the cross-sectional direction.

  Step S103: The front and rear image data specifying unit 34 searches the distance information associated with the pair of the specified modality type and the part of the subject from the distance information stored in the distance information storage unit 33. The distance represented in the distance information stored for the modality type and the part is specified. The front and rear image data specifying unit 34 may specify the distance represented by the distance information stored for the modality type, the part, and the cross-sectional direction.

  Step S104: The front and rear image data specifying unit 34 reads the coordinate system information attached to the key image data G1, thereby specifying the coordinate system set for the plurality of cross-sectional image data including the key image data G1. The front and rear image data specifying unit 34 specifies the slice thickness of the key image data G1 by reading the slice thickness information attached to the key image data G1.

  Step S105: The front and rear image data specifying unit 34 specifies a range included in the specified distance with respect to the front direction and the rear direction perpendicular to the cross section from the specified slice position in the specified coordinate system.

  Step S106: The front and rear image data specifying unit 34 calculates the number of pieces of cross-sectional image data included in the specified range based on the specified distance and the specified slice thickness.

  Step S107: The front and rear image data specifying unit 34 specifies the front and rear image data G2 by extracting cross-sectional image data corresponding to the calculated number of data. The front and rear image data specifying unit 34 outputs the specified image UID of the front and rear image data G2 and the image UID of the key image data G1 to the attachment unit 35.

  Step S108: The attachment unit 35 attaches the preceding and following image data G2 together with the key image data G1 to the interpretation report data. At this time, based on the UID of the front and rear image data G2 and the image UID of the key image data G1 from the front and rear image data specifying unit 34, the key image data G1 and the key image data G1 are selected from the cross-sectional image data stored in the image data storage unit 21. The front and rear image data G2 is specified. The attachment unit 35 attaches the specified key image data G1 and the preceding and following image data G2 to the interpretation report data in association with the image reference field related to the attachment instruction.

  According to the interpretation report system of the first embodiment, the preceding and following image data G2 is attached to the interpretation report in conjunction with the attachment instruction for attaching the key image data G1. As a result, when the requesting doctor or the like refers to the interpretation report, or when the interpretation doctor refers to the interpretation report being created, the requesting doctor or the interpretation doctor simply refers to the cross-sectional image close to the slice position of the key image. be able to. Therefore, it is possible to provide an interpretation report system that can easily create and refer to an interpretation report.

  In addition, according to the interpretation report system of the first embodiment, the range related to the number of data of the attached front and rear image data G2 is for each pair of modality type and subject part, or modality type and subject part. And for each combination of cross-sectional directions. These pairs and combinations vary widely depending on the examination content and interpretation purpose of the interpretation report.

  Further, the number of data of the front and rear image data G2 to be attached is automatically calculated based on this range and the slice thickness. Therefore, it is possible to easily create and refer to an interpretation report while automatically extracting and attaching a number of front and rear images corresponding to the examination content and interpretation purpose of the interpretation report.

  Further, since the key image data G1 and the preceding and following image data G2 are attached to the interpretation report data, the requesting doctor is close to the slice position of the key image even when the image viewer is not installed in the reference terminal. A cross-sectional image can be referred to easily.

  In addition, the cross-sectional images at slice positions close to each other may be similar to each other. The interpretation report system of this embodiment displays the key image and the preceding and following images in a display mode that can be identified. Therefore, according to the interpretation report system of this embodiment, the interpretation doctor and the requesting doctor can refer to the interpretation report while easily grasping the type of the displayed image.

<Third Embodiment>
FIG. 10 is a block diagram illustrating a configuration of the image interpretation report creating apparatus 3 according to the third embodiment. The interpretation report creation apparatus 3 according to this embodiment reflects the same coordinates as the partial area specified in the key image data G1 in the front and rear image data G2, and interprets the image data representing the partial area of the front and rear image data G2 as interpretation report data. It is possible to attach to. Hereinafter, content different from the first embodiment will be mainly described. Further, description of the same contents as in the first embodiment may be omitted.

  When receiving the designation of the partial area of the key image data G1, the partial area storage unit 38 stores partial area coordinate information representing the coordinates of the partial area. An interpreting physician may designate a partial region representing a lesioned part in a key image in order to make a lesioned part easily understood by a referrer such as a requesting doctor. Further, an image representing this partial area (partial image of the key image) may be enlarged and displayed in an image reference field different from the key image. The designation of the partial area is performed, for example, via the operation unit 31 configured with a pointing device such as a mouse. The partial area storage unit 38 stores the partial area coordinates representing the coordinates of the designated partial area in association with the image UID of the key image data G1.

  The attachment unit 35 interprets the key partial image data representing the image of the partial area in the key image data G1, and the front and rear partial image data representing the partial image corresponding to the coordinates of the partial area coordinate information in the front and rear image data G2. Attach to data. FIG. 11 is a conceptual diagram showing processing by the attachment unit 35. For example, when an image interpretation report is created, the image interpretation doctor designates a desired image as a key image and gives an instruction to attach to the desired image reference field R1 (see the image interpretation report creation screen W2). The attachment unit 35 uses key image data from the cross-sectional image data stored in the image data storage unit 21 based on the image UID of the front and rear image data G2 from the front and rear image data specifying unit 34 based on the image UID of the image data. G1 and front and rear image data G2 are specified.

  Further, the attachment unit 35 searches the partial region storage unit 38 for the partial region coordinates stored in association with the image UID based on the image UID of the key image data G1. When the partial region coordinates stored in association with the image UID are stored in the partial region storage unit 38, the attachment unit 35 extracts the partial image of the partial region coordinates from the key image data G1, and the key portion It is specified as image data SR1. In addition, the attachment unit 35 extracts a partial image having coordinates corresponding to the partial region coordinates from each of the front and rear image data G2, and specifies the front and rear partial image data SR2.

  The attachment unit 35 attaches the specified key image data G1 and the preceding and following image data G2 to the interpretation report data in association with the image reference field R1 related to the attachment instruction. The attachment unit 35 attaches the specified key partial image data SR1 and front and rear partial image data SR2 to the image interpretation report data in association with the image reference field R2. The position of the image reference column R2 is designed as appropriate.

  The attachment unit 35 includes the image UID and slice position of the attached key image data G1, the image UID and slice position of the preceding and following image data G2, the information of the associated image reference field R1, and the attached key partial image data. The attached information indicating the slice position of SR1, the slice position of the front and rear partial image data SR2, and the information of the associated image reference field R2 is output to the display control unit 36.

  Note that the attachment unit 35 performs the same processing as in the first embodiment when the partial region coordinates stored in association with the image UID are not stored in the partial region storage unit 38.

  Whenever the display control unit 36 receives a predetermined image turning instruction based on the attached information from the attachment unit 35, the display control unit 36 includes an image group including the key image data G1, or the key partial image data SR1 and the front and rear partial image data. A partial image group consisting of SR2 is turned over and displayed. The turn display order includes the image UID and slice position of the key image data G1 included in the attached information, the image UID and slice position of the preceding and following image data G2, the information of the associated image reference field R1, and the attached key. It is determined based on the slice position of the partial image data SR1, the slice position of the front and rear partial image data SR2, and the information in the associated image reference field R2.

  Further, the display control unit 36 may display a slider that represents the slice position of the image displayed on the forefront of the image group or the partial image group. FIG. 12 is a schematic diagram illustrating a display example of an image group or a partial image group in an interpretation report. The display control unit 36 displays the slider SL1 and the movement axis A1 to which the slider SL1 can move in the vicinity of the displayed image. Further, the display control unit 36 displays a slider SL2 for switching between the display of the image group and the display of the partial image group and a movement axis A2 to which the slider SL2 can move in the vicinity of the displayed image. On the movement axis A2, a position associated with an image group and a position associated with a partial image group are individually assigned.

  The display control unit 36 receives an instruction to move the slider SL2 as a switching instruction, and switches between image group display and partial image group display. For example, an operator such as an interpreting doctor or a requesting doctor performs a drag operation for moving the slider SL2 along the movement axis A2 using the operation unit 31 such as a mouse. The display control unit 36 receives this drag operation as a switching instruction, and switches between the display of the image group and the display of the partial image group. At this time, the display control unit 36 refers to the position assigned on the movement axis A2 and the position of the slider SL2, and interlocks with the position on the movement axis A2 of the slider SL2 to display the image group and the partial image. Switch between group display.

A specific display mode is appropriately designed.

  Further, the display control unit 36 may display text information indicating the type of the image displayed in the foreground in the vicinity of the image. For example, when the key image is displayed on the forefront, the display control unit 36 displays text information “key image” in the vicinity of the key image. When the front and rear images are displayed on the foreground, the display control unit 36 displays text information “front and rear images” in the vicinity of the front and rear images. When the key partial image is displayed in the foreground, the display control unit 36 displays text information “key partial image” or “enlarged partial image (key image)” in the vicinity of the key partial image. When the front and rear partial images are displayed on the forefront, the display control unit 36 displays text information “front and rear partial images” or “enlarged partial images (front and rear images)” in the vicinity of the front and rear partial images.

  The display control unit 36 includes the image UID and slice position of the key image data G1 included in the attached information, the image UID and slice position of the front and rear image data G2, and the slice position and front and rear partial images of the attached key partial image data SR1. The display mode is changed by specifying the type of the image displayed in the foreground while referring to the slice position of the data SR2 and the above-described image turning instruction and switching instruction.

  FIG. 13 is a flowchart showing an operation in which the interpretation report system according to the third embodiment attaches key image data G1, front and rear image data G2, key partial image data SR1, and front and rear partial image data SR2 to the interpretation report data.

  The processing from step S301 to step S307 is the same as the processing from step S101 to step S107 in the example of FIG.

  Step S308: The attachment unit 35 searches the partial region storage unit 38 for the partial region coordinates stored in association with the image UID based on the image UID of the key image data G1. When the partial region coordinates stored in association with the image UID are stored in the partial region storage unit 38 (step S308; YES), the operation of this embodiment proceeds to step S309. When the partial area coordinates stored in association with the image UID are not stored in the partial area storage unit 38 (step S308; NO), the operation of this embodiment proceeds to step S311.

  Step S309: The attachment unit 35 extracts the partial image of the partial region coordinates from the key image data G1, and specifies it as the key partial image data SR1. In addition, the attachment unit 35 extracts a partial image having coordinates corresponding to the partial region coordinates from each of the front and rear image data G2, and specifies the front and rear partial image data SR2.

  Step S310: The attachment unit 35 attaches the specified key image data G1 and the preceding and following image data G2 to the interpretation report data in association with the image reference field R1 related to the attachment instruction. The attachment unit 35 attaches the specified key partial image data SR1 and front and rear partial image data SR2 to the image interpretation report data in association with the image reference field R2.

  The process of step S311 is the same as the process of step S108 in the example of FIG.

  An interpreting physician may designate a partial region representing a lesioned part in a key image in order to make a lesioned part easily understood by a referrer such as a requesting doctor. According to the interpretation report system according to the third embodiment, key partial image data SR1 representing a partial area and front and rear partial image data SR2 corresponding to the partial area can be attached to the interpretation report in conjunction with the attachment instruction. .

  Moreover, the interpretation report system of this embodiment displays the key image, the front and rear images, the key partial image, and the front and rear partial images in a display mode that can be identified. Therefore, according to the interpretation report system of this embodiment, the interpretation doctor and the requesting doctor can refer to the interpretation report while easily grasping the type of the displayed image.

<Fourth Embodiment>
FIG. 14 is a block diagram illustrating a configuration of the image interpretation report creating apparatus 3 according to the fourth embodiment. The interpretation report creating apparatus 3 according to this embodiment is configured to be able to attach the slice image data at the slice position corresponding to the slice position of the key image to the interpretation report data. Hereinafter, content different from the first embodiment will be mainly described. Further, description of the same contents as in the first embodiment may be omitted.

For example, the past image search unit 39 reads the slice position information included in the supplementary information of the designated key image data G1, and specifies the slice position of the key image data G1. The past image search unit 39 reads the incidental information of the designated key image data G1 and identifies the subject ID. The past image search unit 39 reads the date / time information of the designated key image data G1, and specifies the date / time when the key image data G1 was acquired.

  In addition, the past image search unit 39 reads the modality information included in the supplementary information of the key image data G1, specifies the modality type of the key image data G1, and stores the part information included in the supplementary information of the key image data G1. By reading, the region of the subject may be specified, and the cross-sectional direction information of the key image data G1 may be specified by reading the cross-sectional direction information of the key image data G1.

  The past image search unit 39 has previously determined the slice position of the subject among the plurality of past cross-sectional image data stored in the image data storage unit 21 based on the identified subject ID, date and slice position. The acquired position-corresponding past image data is searched. At this time, the past image search unit 39 refers to the identified subject ID, date / time, and slice position, and the incidental information of the cross-sectional image data stored in the image data storage unit 21, so that the position-corresponding past image data Search for. As a result, cross-sectional image data acquired in the past for the same subject and slice position as the key image data G1 of the interpretation report being created is retrieved as position-corresponding past image data. The past image search unit 39 outputs the image UID of the searched position-corresponding past image data to the front and rear image data specifying unit 34.

  The past image search unit 39 also uses the same subject ID as the key image data G1 of the interpretation report being created based on the identified subject ID, date and time, slice position, modality type, subject part, and cross-sectional direction. The cross-sectional image data acquired in the past with respect to the slice position, modality type, the part of the subject, and the cross-sectional direction may be searched as position-corresponding past image data.

  The past image search unit 39 may search for cross-sectional image data similar to the key image data G1 as position-corresponding past image data by a known image correlation method or the like. The coordinate system may be different between the cross-sectional image data group including the key image data G1 and the cross-sectional image data group including cross-sectional image data acquired in the past for the same subject and slice position as the key image data G1. Because.

  When the position-corresponding past image data is not stored in the image data storage unit 21, that is, when the past image searching unit 39 cannot retrieve the position-corresponding past image data, the position-corresponding past image data There is no image UID. Therefore, the past image search unit 39 stands by. At this time, the interpretation report creating apparatus 3 of this embodiment performs the same processing as that of the first embodiment.

Then, the front and rear image data specifying unit 34 specifies the past front and rear image data G4 from a plurality of past cross-sectional image data including the position-corresponding past image data by the same processing as in the first embodiment. The front-rear image data specifying unit 34 outputs the image UID of the specified past image data G4 and the image UID of the position-corresponding past image data to the attachment unit 35.

  The attachment unit 35 attaches the position-corresponding past image data and the past preceding and following image data G4 together with the key image data G1 and the preceding and following image data G2 to the interpretation report data. FIG. 15A is a conceptual diagram showing processing by the attachment unit 35. For example, when an image interpretation report is created, the image interpretation doctor designates a desired image as a key image and gives an instruction to attach to the desired image reference field R1 (see the image interpretation report creation screen W2). The attachment unit 35 uses key image data from the cross-sectional image data stored in the image data storage unit 21 based on the image UID of the front and rear image data G2 from the front and rear image data specifying unit 34 based on the image UID of the image data. G1 and front and rear image data G2 are specified.

  Step S408: The past image search unit 39 corresponds to the slice position among a plurality of past slice image data acquired in the past based on the slice position of the key image data G1 and the subject ID that can identify the subject. The position corresponding past image data G3 which is the cross-sectional image data of the slice position to be searched is searched. When the position-corresponding past image data G3 is stored in the image data storage unit 21 (step S408; YES), the operation of this embodiment proceeds to step S409. When the position-corresponding past image data G3 is not stored in the image data storage unit 21 (step S408; NO), the operation of this embodiment proceeds to step S411.

  Step S409: The front and rear image data specifying unit 34 receives the image UID from the past image search unit 39 and specifies the position-corresponding past image data G3 from the cross-sectional image data stored in the image data storage unit 21. Based on the slice position of the position-corresponding past image data G3, the slice thicknesses of the plurality of past cross-sectional image data including the position-corresponding past image data G3, and the distance represented by the distance information. Past past image data G4 included in the range of the past cross-sectional image data. The front and rear image data specifying unit 34 outputs the specified image UID of the previous and previous image data G4 and the image UID of the position corresponding past image data G3 to the attachment unit 35.

  Step S410: The attachment unit 35 uses the UID and key of the front and rear image data G2 from the front and rear image data specifying unit 34 based on the image UID of the image data, from among the cross-sectional image data stored in the image data storage unit 21. The key image data G1 and the front and rear image data G2 are specified. Furthermore, the attachment unit 35 selects the position-corresponding past image data from the cross-sectional image data stored in the image data storage unit 21 based on the image UID of the position-corresponding past image data G3 and the image UID of the previous and subsequent image data G4. G3 and previous and subsequent image data G4 are specified. The attachment unit 35 attaches the specified key image data G1 and the preceding and following image data G2 to the interpretation report data in association with the image reference field R1 related to the attachment instruction. Further, the attachment unit 35 attaches the specified position-corresponding past image data G3 and the past preceding and following image data G4 to the image interpretation report data in association with the image reference field R3.
