JP7552372B2 - Photographing support device, photographing support method, and program - Google Patents

Description

The present invention relates to a photography support device, a photography support method, and a program.

Conventionally, in radiographic examinations using radiation such as X-rays, the examiner (radiologist) operates the imaging device to take images of the examinee (patient). During the examination, the examinee needs to assume a position appropriate to the area being examined, so the examiner instructs the examinee on the appropriate position by explaining verbally or by touching the area to be examined and guiding the examinee into a position appropriate for the examination.

Even if subjects are given verbal instructions about the position, it is difficult for them to imagine the correct position. For this reason, photos of example positions may be posted in the imaging room, but the photos displayed will not change depending on the part of the body being examined.

In addition, to reduce the time required for the examiner to give instructions and support to the subject during imaging, a radiology information system has been proposed in which the examiner hands over a PDA terminal to the subject before the examination, and the subject checks in advance moving and still images explaining the position displayed on the PDA terminal (see Patent Document 1). This system associates and stores the subject's physical information (movement method, infectious diseases, contrast agent contraindications, allergies, etc.) that should be taken into consideration during the radiology examination with supplementary examination information including an explanation of the position to be taken during the examination, extracts the supplementary examination information that corresponds to the subject's physical information, and presents the extracted supplementary examination information to the subject.

In addition, in a test support system for subjects consisting of a test instruction operation terminal (tablet-type personal computer) operated by the test provider and a test instruction display terminal (head-mounted display) that displays instructions for changing the subject's body position, a technology has been proposed in which the body position instructions selected by the test provider on the test instruction operation terminal are displayed on the test instruction display terminal on the subject's side (see Patent Document 2).

JP 2007-215611 A Patent No. 6174231

However, with the technology described in Patent Document 1, supplementary test information such as body position is presented to the subject before entering the imaging room, and no consideration is given to the subject checking the supplementary test information in the imaging room during the examination. In other words, with the technology described in Patent Document 1, the subject is called into the imaging room after checking the supplementary test information, and the examination is then conducted, so the subject does not learn the supplementary test information, including body position, through video or still images, etc., during the examination.

In addition, with the technology described in Patent Document 2, the instructions selected by the examiner on the examination instruction operation terminal are displayed on the examination instruction display terminal on the examinee's side, but what is provided to the examinee is an image of the body orientation, text characters, and voice instructions, not an image of the body position itself. In addition, once the examination area is decided, it is thought that the candidate body positions for photographing that examination area will be narrowed down, but with the technology described in Patent Document 2, the examiner must select the body orientation each time on the examination instruction operation terminal, and candidate body positions are not automatically selected according to the examination area.

The present invention was made in consideration of the problems with the conventional technology described above, and aims to present the subject with an easy-to-understand posture in the imaging room during the examination.

In order to solve the above problem, the invention described in claim 1 is an imaging support device that supports an imaging examination of a subject through operation by an examination administrator, and includes a memory unit that stores an examination site and a body position image indicating a body position when the examination site is imaged in association with each other, and stores the body position image in association with a display method indicating repeated display or one-time display , and a control unit that acquires the examination site related to the imaging examination, acquires a body position image corresponding to the acquired examination site from the memory unit, acquires a display method corresponding to the acquired body position image from the memory unit, and presents the acquired body position image to the subject via an image output unit provided in the imaging room when the imaging examination is performed, so as to display repeatedly or once based on the acquired display method.

The invention described in claim 2 is the imaging support device described in claim 1, in which, when a plurality of body position images are associated with the examination site in the storage unit, the control unit displays each of the plurality of body position images corresponding to the examination site related to the imaging examination as a candidate on an operation terminal operated by the examination implementer, accepts selection of one of the displayed body position images from the plurality of candidates from the operation terminal, and presents the selected body position image to the subject via the image output unit.

The invention described in claim 3 is the imaging support device described in claim 1 or 2, in which the control unit causes an operation terminal operated by the examination person to display an image that is the same as the body position image presented to the subject by the image output unit when the imaging examination is performed.

The invention described in claim 4 is the imaging support device described in any one of claims 1 to 3, in which the control unit acquires examination information from an electronic medical record system and acquires the examination area related to the imaging examination from the acquired examination information.

The invention described in claim 5 is an imaging support method in an imaging support device that supports an imaging examination of a subject through operation by an examination implementer, and that has a memory unit that stores an examination site and a body position image indicating a body position when the examination site is photographed in association with each other, and that stores the body position image and a display method indicating repeated display or one-time display in association with each other, the method including the steps of: acquiring an examination site related to the imaging examination; acquiring a body position image corresponding to the acquired examination site from the memory unit; acquiring a display method corresponding to the acquired body position image from the memory unit; and presenting the acquired body position image to the subject by an image output unit provided in an imaging room when the imaging examination is performed, so as to be displayed repeatedly or once based on the acquired display method.

The invention described in claim 6 is a program for enabling a computer of an imaging support device that supports an imaging examination of a subject through operation by an examination operator to realize a function of acquiring an examination site related to the imaging examination, a function of acquiring a posture image corresponding to the acquired examination site from the memory unit, a function of acquiring a display method corresponding to the acquired posture image from the memory unit, and a function of presenting the acquired posture image to the subject by an image output unit provided in the imaging room when the imaging examination is performed so that the acquired posture image is displayed repeatedly or once based on the acquired display method .

The present invention makes it possible to clearly present the subject's body position in the imaging room during the examination.

The following describes an embodiment of the photography support device according to the present invention. However, the scope of the invention is not limited to the illustrated example.

[First embodiment]
First, the first embodiment will be described.
FIG. 1 shows the system configuration of a medical facility system 100 .
As shown in FIG. 1, the medical facility system 100 is composed of an electronic medical record server 10, a RIS (Radiology Information System) server 20, an image management server 30, an examiner terminal 40, a modality 50, etc., and is connected to be able to perform data communication via a communication network N such as a LAN (Local Area Network). Each device constituting the medical facility system 100 complies with the HL7 (Health Level Seven) or DICOM (Digital Image and Communications in Medicine) standard, and communication between each device is performed in accordance with HL7 or DICOM. The number of the examiner terminal 40 and the modality 50 is not particularly limited. The electronic medical record server 10, the RIS server 20, and the image management server 30 may be cloud servers provided in a cloud environment.

The electronic medical record server 10 generates electronic medical record information that records medical treatments and diagnosis results for patients in response to operational instructions from a client terminal (not shown) used by a doctor. The electronic medical record server 10 and the client terminal constitute an electronic medical record system.

The RIS server 20 manages information within the radiology department, such as appointments for examinations and treatments using radiation equipment, and examination results. The RIS server 20 and client terminals such as the examination implementer terminal 40 make up a radiology information system.

The image management server 30 stores image data of medical images generated in the modality 50 and manages the data for each patient. An example of the image management server 30 is a picture archiving and communication system (PACS). When an external device requests the acquisition of a medical image, the image management server 30 transmits the requested medical image to the external device in response to the acquisition request.

The examiner terminal 40 is a computer device such as a PC (Personal Computer) used by the examiner (radiologist) and is installed in the examination operation room. The examiner operates the examiner terminal 40 to control the modality 50 and perform imaging examinations, etc.

The modality 50 is installed in the imaging room. The modality 50 is an image generating device such as an X-ray device (DR, CR), an ultrasound diagnostic device (US), a CT, or an MRI, and generates medical images obtained by photographing a subject. The modality 50 writes additional information (patient information, examination information, etc.) to the header of the image file of the medical image in accordance with the DICOM standard, thereby attaching additional information to the medical image.

The radiography room is also provided with an image output unit 60 connected to the test implementer terminal 40. The image output unit 60 outputs a body position image to inform the subject of his/her body position. The image output unit 60 may be connected to the test implementer terminal 40 by a cable or the like, or may be connected wirelessly.

2 shows an example of the installation of the image output unit 60 in a photography room. As the image output unit 60, a display 60A and a projector 60B are installed in the photography room.
The display 60A is configured with a monitor such as an LCD (Liquid Crystal Display), and displays body position images and the like.
The projector 60B includes a light source, a lens, and the like, and projects a body posture image, etc., onto a projection target such as a wall surface or a screen in the imaging room.
The display 60A and the projector 60B are installed at positions where the subject 70 can confirm the body posture images output by the display 60A and the projector 60B when the subject 70 is imaged by the modality 50. It is not necessary to install both the display 60A and the projector 60B, and it is sufficient to install either one of them.

FIG. 3 shows the functional configuration of the RIS server 20.
As shown in FIG. 3, the RIS server 20 includes a control unit 21, a communication unit 22, a timer unit 23, a storage unit 24, etc., and each unit is connected to each other via a bus 25.

The control unit 21 is composed of a CPU (Central Processing Unit), RAM (Random Access Memory), etc., and controls the overall processing of each part of the RIS server 20. Specifically, the CPU reads out various processing programs stored in the storage unit 24, expands them in the RAM, and performs various processes in cooperation with the programs.

The communication unit 22 is configured with a network interface, etc., and transmits and receives data to and from external devices such as the test implementer terminal 40 connected via the communication network N.

The clock unit 23 has a clock circuit (RTC: Real Time Clock) that counts the current date and time and outputs it to the control unit 21.

The storage unit 24 is configured with a HDD (Hard Disk Drive), non-volatile memory, etc., and stores various processing programs and various data required for executing the programs. For example, the storage unit 24 has a database 241, which includes an examination type master table T1, an examination area master table T2, a body position master table T3, an image master table T4, and an association table T5. The storage unit 24 also stores an examination information management table T6.

The examination type master table T1 is a table for managing examination types (X-ray examination, CT examination, MRI examination, etc.). As shown in FIG. 4, the examination type master table T1 associates each examination type with an examination type ID, examination type name, update date and time, etc. The examination type ID is identification information for the examination type. The examination type name is the name of the examination type. The update date and time is the date and time when each record in the examination type master table T1 was updated.

The examination area master table T2 is a table for managing examination areas (chest, abdomen, head, etc.). As shown in FIG. 5, the examination area master table T2 associates each examination area with an examination area ID, examination area name, examination type ID, update date and time, etc. The examination area ID is identification information for the examination area. The examination area name is the name of the examination area. The examination type ID is the examination type ID of the examination type related to the imaging examination performed on the examination area. The update date and time is the date and time when each record in the examination area master table T2 was updated.
In the examination portion master table T2, an examination type ID is associated with each examination portion ID, so that when an examination portion ID is specified, it is determined which examination (examination type) will be performed and which portion will be imaged.

The posture master table T3 is a table for managing postures (standing front, standing side, lying front, etc.). As shown in FIG. 6, the posture master table T3 associates each posture with a posture ID, posture name, update date and time, etc. The posture ID is identification information for the posture. The posture name is the name of the posture. The update date and time is the date and time when each record in the posture master table T3 was updated.

The image master table T4 is a table for managing posture images. As shown in Fig. 7, the image master table T4 associates an image ID, an image name, a storage location of the image data, an update date and time, etc. with each posture image. The image ID is identification information of the posture image. The image name is the name of the posture image (such as a file name). The storage location of the image data is a path name indicating the storage location of the file of the image data of the posture image. The update date and time is the date and time when each record in the image master table T4 was updated.
For example, the body position image with image ID "1" and the body position image with image ID "2" are images showing the body position when photographing the "chest" in a "standing front" position, but image ID "1" is a still image and image ID "2" is a moving image.

The association table T5 is a table for defining associations between an examination site, a body position, and a body position image. As shown in Fig. 8, the association table T5 stores an examination site ID, an examination site name, a body position ID, a body position name, an image ID, an image name, a subject-side display method, an examiner-side display method, etc., in association with each other for each examination site, body position, and body position image.
The examination part ID and examination part name are the examination part ID and examination part name of the examination part included in the association, respectively.
The posture ID and posture name are the posture ID and posture name of the posture included in the association, respectively.
The image ID and image name are the image ID and image name, respectively, of the posture image included in the association.

The subject-side display method is a display method for presenting the body position image to the subject. "Repeat display" or "single display" is set as the subject-side display method. "Repeat display" is a display method for repeatedly displaying the body position image. "Single display" is a display method for displaying the body position image once. Here, two types of subject-side display methods are provided, but three or more types of methods may be provided.

The tester's display method is the display method when presenting the body position image to the tester. As the tester's display method, "display of same content" or "mark in display" is set. "Display of same content" is a display method in which the tester's side displays a body position image with the same content as the subject's side. "Mark in display" is a display method in which the tester's side displays a mark indicating that the body position image is being displayed on the subject's side (the body position image is not displayed). Here, two types of methods are provided as the tester's display method, but three or more types of methods may be provided.

FIG. 9 is an image diagram showing the relationships between the tables T1 to T5 in the database 241. As shown in FIG.
In the association table T5, each record includes an "examination region ID" from the examination region master table T2, a "position ID" from the body position master table T3, and an "image ID" from the image master table T4. That is, the storage unit 24 that stores the association table T5 stores an examination region and a body position image indicating a body position when the examination region is photographed in association with each other.

The examination information management table T6 is a table for managing scheduled and registered imaging examinations. As shown in Fig. 10, the examination information management table T6 stores an examination ID, an examination type name, an examination part name, status information, etc. in association with each imaging examination.
The examination ID is the examination ID of the imaging examination.
The examination type name is the name of the examination type related to the imaging examination.
The examination region name is the name of the examination region related to the imaging examination.
The status information is information that indicates the progress of the examination, such as "before acceptance,""accepted,""performed," etc. "Before acceptance" is the state before the examination is accepted and registered. "Accepted" is the state after the examination is accepted and registered, but before the examination is conducted. "Performed" is the state after the examination is conducted.

The control unit 21 acquires the examination area related to the imaging examination, acquires the body position image corresponding to the acquired examination area from the storage unit 24, and presents the acquired body position image to the subject by the image output unit 60 provided in the imaging room when the imaging examination is performed. Specifically, the control unit 21 causes the image output unit 60 to output the body position image via the examination implementer terminal 40.

When multiple body position images are associated with an examination site in the memory unit 24, the control unit 21 displays each of the multiple body position images corresponding to the examination site related to the imaging examination as a candidate on the examination implementer terminal 40 (operation terminal) operated by the examination implementer, accepts selection of one of the displayed multiple candidates from the examination implementer terminal 40, and presents the selected body position image to the subject via the image output unit 60.

The control unit 21 refers to the association table T5, and when the display method on the test implementer side of the record corresponding to the posture image to be presented to the subject is "display the same content," when the imaging test is performed, causes the test implementer terminal 40 operated by the test implementer to display the same image as the posture image to be presented to the subject by the image output unit 60.

FIG. 11 shows the functional configuration of the test implementer terminal 40 .
As shown in FIG. 11, the test implementer terminal 40 is configured with a control unit 41, an operation unit 42, a display unit 43, a communication unit 44, a memory unit 45, an IF (InterFace) unit 46, etc., and each unit is connected by a bus 47.

The control unit 41 is composed of a CPU, RAM, etc., and controls the overall processing of each unit of the test implementer terminal 40. Specifically, the CPU reads out various processing programs stored in the storage unit 45, loads them into the RAM, and performs various processes in cooperation with the programs.

The operation unit 42 is configured with a keyboard equipped with cursor keys, letter/number input keys, various function keys, etc., and a pointing device such as a mouse, and outputs operation signals input by key operations on the keyboard or mouse operations to the control unit 41. The operation unit 42 may also be equipped with a touch panel on the display screen of the display unit 43, in which case it outputs instruction signals input via the touch panel to the control unit 41.

The display unit 43 is configured with a monitor such as an LCD, and displays various screens according to the instructions of the display signal input from the control unit 41. The display unit 43 displays an operation screen operated by the test implementer and body position images.

The communication unit 44 is configured with a network interface or the like, and transmits and receives data to and from external devices connected via the communication network N.

When the test implementer operates the operation unit 42 on the test implementer terminal 40 to select one of the test information (the test information to be implemented) from the test information displayed on the accepted test information list screen (step S32), the control unit 41 sends information indicating the selected test information to the RIS server 20 via the communication unit 44.
The control unit 21 of the RIS server 20 acquires information indicating the selected test information from the test implementer terminal 40 via the communication unit 22 .

Next, the control unit 21 transmits display data for the test implementation screen to the test implementer terminal 40 via the communication unit 22 .
In the test implementer terminal 40, a test implementation screen is displayed on the display unit 43 (step S33).

Then, the test provider guides the subject to the imaging room (step S34). The subject enters the imaging room.

Next, the control unit 21 of the RIS server 20 acquires the test type and test site included in the test information selected in step S32 (step S35). Specifically, the control unit 21 acquires the test type and test site of the record corresponding to the selected test information in the test information management table T6.

Next, the control unit 21 identifies the examination part ID corresponding to the acquired examination type and examination part (step S36). Specifically, the control unit 21 acquires an examination type ID corresponding to the "examination type" of the selected examination information from the examination type master table T1. Then, the control unit 21 acquires an examination part ID corresponding to the combination of this examination type ID and the "examination part" of the selected examination information from the examination part master table T2.

Next, the control unit 21 identifies the body position and body position image corresponding to the identified examination part ID based on the association table T5 (step S37). Specifically, the control unit 21 extracts records in the association table T5 in which the "Examination part ID" field is the examination part ID identified in step S36, and sets the image identified by the "Image ID" included in the extracted record as a candidate for the body position image.

Next, the control unit 21 transmits display data for displaying candidates for the body position image to the test implementer terminal 40 via the communication unit 22 .
In the test implementer terminal 40, the candidate body position images are displayed on the display unit 43 (step S38). The method of displaying the candidate body position images may be any method as long as the test implementer can distinguish between the multiple candidates. For example, as the candidate body position images, the body position images themselves (still images, moving images) may be displayed, or simple images showing the body positions or the image names of the body position images may be displayed.

Figure 16 shows an example of the test implementation screen 431 displayed on the display unit 43 of the test implementer terminal 40. The test implementation screen 431 includes a position image candidate display area 431A, a selected position image display area 431B, a display button B1, a back button B2, etc.

The position image candidate display area 431A displays position image candidates 71 and 72 corresponding to the examination type and examination part included in the selected examination information. The examiner selects one of the position images from the displayed candidates 71 and 72.
The selected posture image display area 431B displays the posture image selected in the posture image candidate display area 431A. When the left posture image (candidate 71) is selected in the posture image candidate display area 431A, the left posture image is displayed in the selected posture image display area 431B.
The display button B1 is a button for instructing the image output unit 60 in the imaging room to start displaying the body position image.
The back button B2 is a button for returning to the screen before selecting the examination information (the accepted examination information list screen).

When the test implementer selects one of the candidate posture images displayed on the display unit 43 by operating the operation unit 42 on the test implementer terminal 40 (step S39), the control unit 41 transmits information indicating the selected posture image (image ID, etc.) to the RIS server 20 via the communication unit 44.
The control unit 21 of the RIS server 20 performs a posture image display process (step S40) when it acquires information indicating the selected posture image from the test implementer terminal 40 via the communication unit 22. The posture image display process is a process for displaying the selected posture image.
The control unit 21 obtains the “storage location of image data” corresponding to information indicating the selected posture image (such as an image ID) from the image master table T4, and obtains the posture image from the memory unit 24 based on this “storage location of image data”.

Now, with reference to FIG. 17, the body posture image display process will be described.
The control unit 21 of the RIS server 20 acquires, from the association table T5, the subject-side display method and the tester-side display method corresponding to the body position image (image ID, image name) selected in step S39 (step S51).

Next, the control unit 21 determines whether the subject-side display method acquired in step S51 is "repeated display" (step S52).
If the subject-side display method is “repeated display” (step S52; YES), the control unit 21 transmits display data to the test implementer terminal 40 for repeatedly displaying the selected body position image on the subject side.
The control unit 41 of the test implementer terminal 40 causes the image output unit 60 in the radiography room to repeatedly display the selected body position image based on the display data received from the RIS server 20 (step S53). The subject, in the radiography room, looks at the body position images repeatedly displayed by the image output unit 60 and recognizes the body position that the subject should take.

In step S52, if the subject-side display method is not “repeated display” (step S52; NO), that is, if the subject-side display method is “single display”, the control unit 21 transmits display data for displaying the selected body position image once on the subject side to the test implementer terminal 40.
The control unit 41 of the test implementer terminal 40 causes the image output unit 60 in the radiography room to display the selected body position image once (step S54) based on the display data received from the RIS server 20. The subject, in the radiography room, looks at the body position image displayed once by the image output unit 60 and recognizes the body position the subject should take.

After step S53 or step S54, the control unit 21 of the RIS server 20 determines whether the test implementer side display method acquired in step S51 is "display same contents" (step S55).
If the display method on the test implementer side is “display the same content” (step S55; YES), the control unit 21 sends an instruction to the test implementer terminal 40 to display a posture image on the test implementer side with the same content as on the subject side.
The control unit 41 of the test implementer terminal 40 causes the display unit 43 to display a body position image having the same content as that of the subject side (step S56), based on the instruction received from the RIS server 20. The test implementer can check the body position image having the same content as that of the subject side in the test operation room.

In step S55, if the display method on the test implementer side is not "display same content" (step S55; NO), that is, if the display method on the test implementer side is "displaying mark", the control unit 21 transmits display data for displaying the displaying mark on the test implementer side to the test implementer terminal 40.
The control unit 41 of the test implementer terminal 40 causes the display unit 43 to display a display mark based on the display data received from the RIS server 20 (step S57).
After step S56 or step S57, the body posture image display process ends.

The order of steps S52 to S54 and steps S55 to S57 does not matter.

In addition, on the test implementer terminal 40, the display/non-display of the body position image corresponding to the selected imaging test may be changed by operation from the operation unit 42 to a method different from the test implementer's display method that is preset in the association table T5.

18 to 20 show examples of posture images presented to the subject by the image output unit 60 in the imaging room. The posture images may be still images or moving images including intermediate movements up to the final posture.
Fig. 18 is an image showing a standing front chest position. In Fig. 18, a text instruction 81 is displayed along with a subject image 80, which reads, "Place the backs of both hands on your hips and place your chest and shoulders in contact with the imaging board." In addition, an examination part area 82 showing "chest" is displayed on the subject image 80. From Fig. 18, it can be seen that the subject should stand facing the imaging board and place the backs of their hands on their hips.

Figure 19 is an image showing the standing lateral chest position. In Figure 19, a text instruction 84 is displayed along with a subject image 83, stating, "Put both hands behind your head and place your sides in contact with the imaging board." In addition, an examination area 85 indicating "chest" is displayed on the subject image 83. From Figure 19, it can be seen that the subject should stand with the left side of their body against the imaging board and put both hands behind their head.

Fig. 20 is an image showing a supine frontal chest position. In Fig. 20, a subject image 86 is displayed along with a text instruction 87 saying "Lie on the examination table with both arms down." Also displayed on the subject image 86 is an examination site area 88 showing "chest." From Fig. 20, it can be seen that the subject should lie on his/her back on the examination table with both arms down from his/her torso.
In this way, the subject can understand the subject's orientation and arm position relative to the imaging plate and examination table from the body position image.

After the posture image display process (see FIG. 17), the process returns to FIG. 15, and the examiner performs an imaging examination using the modality 50 (step S41).
For example, the modality 50 captures a target area of a subject and generates a medical image in response to an operation by an examiner from the operation unit 42 of the examiner terminal 40. The modality 50 attaches additional information to the generated medical image and transmits it to the image management server 30.
When the image management server 30 receives a medical image from the modality 50, the image management server 30 stores and manages the medical image based on the supplementary information of the medical image.

Next, when the test implementer inputs test implementation information at the test implementer terminal 40 by operating the operation unit 42 (step S42), the control unit 41 transmits the input test implementation information to the RIS server 20 via the communication unit 44. The test implementation information is information related to the implementation of the imaging test related to the test information. For example, the test implementation information includes information that was not known from the prior test registration, such as medicine used when the test was performed.
The control unit 21 of the RIS server 20, upon receiving the test implementation information input from the test implementer terminal 40 via the communication unit 22, registers the test implementation information in the test information management table T6 (step S43). The control unit 21 also changes the status information of the record in the test information management table T6 that corresponds to the selected test information to "Completed."

Next, the examiner makes the subject leave the imaging room (step S44).
This completes the imaging examination processing.

The processing of step S34 may be performed after some or all of the processing of steps S35 to S40. However, if the processing of step S34 is performed after the processing of step S40, the display of the body position image in the imaging room will continue even after the subject enters the imaging room.

Furthermore, in step S37, if there is one body posture image corresponding to the examination region ID, this body posture image is set as the display target, and the processes in steps S38 and S39 can be omitted.
Furthermore, even if there are multiple body position images corresponding to the examination region ID in step S37, all body position images corresponding to the examination region ID may be displayed without selecting a body position image in step S39.

As described above, according to the first embodiment, the RIS server 20 acquires the examination area related to the imaging examination, and presents the body position image (still image, moving image) corresponding to the acquired examination area to the subject by the image output unit 60 installed in the imaging room when the imaging examination is performed, so that the body position can be presented to the subject in an easy-to-understand manner in the imaging room during the examination. For example, the RIS server 20 displays the body position image on the screen of a display 60A installed in the imaging room via the examination implementer terminal 40, or projects it into the imaging room by a projector 60B. Therefore, the subject himself can visually confirm the still image and moving image corresponding to the body position during the examination.

In addition, by presenting the subject with still images, moving images, or other posture images, it is possible to instruct the subject on the posture they should assume, thereby reducing the opportunities for direct contact between the tester and the subject and lowering the risk of infection through contact.
Furthermore, if posture instructions from the person conducting the test were displayed on a head-mounted display, the head-mounted display would be worn directly by the subject, which would pose a high risk of infection through contact; however, in this embodiment, the image output unit 60 does not come into direct contact with the subject, thereby making it possible to avoid the risk of infection through contact.

In addition, in the RIS server 20, in the database 241, the posture images showing the postures corresponding to the examination area can be managed by the master setting. Specifically, in the association table T5, one or more posture images are associated with the examination area, so that once the examination area is determined, one or more posture images corresponding to the examination area can be identified.

In addition, when multiple body position images are associated with an examination site in the memory unit 24 (association table T5), the RIS server 20 can display multiple body position images (candidates) corresponding to the examination site related to the imaging examination on the examination implementer terminal 40, and present a body position image selected from the multiple displayed candidates by the examination implementer terminal 40 to the subject via the image output unit 60.

In addition, when the test implementer side display method for the posture image to be presented to the subject is set to "display same content" in the association table T5, the RIS server 20 causes the test implementer terminal 40 operated by the test implementer to display the same image as the posture image to be presented to the subject by the image output unit 60 during the imaging test, so that the test implementer and the subject, who are in separate locations, can see the same posture image (still image, moving image). In other words, the test implementer can confirm the same image as the posture image presented to the subject.

[Second embodiment]
Next, a second embodiment to which the present invention is applied will be described.
The medical facility system in the second embodiment has the same configuration as the medical facility system 100 shown in the first embodiment, and therefore the configuration will not be illustrated or described. The configuration and processing characteristic of the second embodiment will be described below.

In the second embodiment, the electronic medical record system (a system consisting of an electronic medical record server 10 and a client terminal) and the radiology information system (a system consisting of a RIS server 20 and an examiner terminal 40) work together to enable mutual use of the information held by each system.

The electronic medical record server 10 generates an examination order for requesting an examination for a patient. The examination order includes the person requesting the examination, examination information, and the like.
The test requester is the physician who requests the test.
The examination information includes the examination ID, examination type (X-ray examination, CT examination, MRI examination, etc.), examination area (chest, abdomen, head, etc.), medical department, purpose of the examination, whether or not contrast agent was used, etc., as well as information about the patient (patient ID, patient name, date of birth, age, gender, etc.).

The control unit 21 of the RIS server 20 acquires examination information from the electronic medical record system (electronic medical record server 10), and acquires the examination site related to the imaging examination from the acquired examination information.
The control unit 21 acquires a posture image corresponding to the acquired examination area from the memory unit 24, and presents the acquired posture image to the subject via the image output unit 60 installed in the imaging room when the imaging examination is performed.

Figures 21 and 22 are ladder charts showing the system linkage processing executed in the RIS server 20 and the electronic medical record server 10. In Figures 21 and 22, processing that is mainly performed by human actions is also shown with dashed rectangles.

First, a doctor accesses the electronic medical record server 10 from a client terminal, specifies the patient and the examination content, and inputs examination information (step S61). The electronic medical record server 10 then registers the examination information and transmits the examination information to the RIS server 20 (step S62).

When the control unit 21 of the RIS server 20 receives the test information from the electronic medical record server 10 via the communication unit 22 (step S63), it performs an import process for the test information (step S64). Specifically, the control unit 21 registers the test information received from the electronic medical record server 10 in the test information management table T6. Here, the status information corresponding to the registered test information is in the "before acceptance" state.

Next, when the test implementer inputs reception information for the registered test information by operating the operation unit 42 on the test implementer terminal 40 (step S65), the control unit 41 transmits the input reception information to the RIS server 20 via the communication unit 44.
When the control unit 21 of the RIS server 20 acquires the reception information input from the test implementer terminal 40 via the communication unit 22, the control unit 21 registers the reception information for the corresponding test information (the test information received in step S63) in the test information management table T6 (step S66). Specifically, the control unit 21 changes the status information of the record corresponding to the corresponding test information in the test information management table T6 to "received."

Then, the test provider guides the subject to the imaging room (step S67). The subject enters the imaging room.

Next, the control unit 21 of the RIS server 20 acquires the test type and test area contained in the corresponding test information (step S68).

The processing of steps S69 to S76 is similar to the processing of steps S36 to S43 in the processing during imaging examination in FIG. 15, so a description thereof will be omitted. The body position image display processing of step S73 is also similar to the body position image display processing in FIG. 17.

After step S76, the control unit 21 of the RIS server 20 transmits the test implementation information to the electronic medical record server 10 via the communication unit 22 (step S77).
The electronic medical record server 10 receives the test implementation information from the RIS server 20 (step S78), associates it with the test information registered in the electronic medical record server 10, and records that the target test has been implemented.

Next, the examiner makes the subject leave the imaging room (step S79).
This completes the system linkage process.

As described above, according to the second embodiment, similar to the first embodiment, it is possible to clearly present the subject's body position in the imaging room during the examination.

The RIS server 20 also works in conjunction with the electronic medical record system (electronic medical record server 10) to obtain examination information from the electronic medical record server 10 and obtain the examination area related to the imaging examination from the obtained examination information. Since information held by other systems can be used, the examiner does not need to specify the examination area, etc.

The above descriptions of the embodiments are examples of the photography support device according to the present invention, and are not limited to these. The detailed configurations and operations of each component may be modified as appropriate without departing from the spirit of the present invention.

For example, in each of the above embodiments, a case has been described in which the examination area is obtained from examination information of an imaging examination scheduled and registered in the RIS server 20 or examination information obtained from the electronic medical record server 10. However, the examination area related to the imaging examination may be obtained by the examiner specifying the examination area when the imaging examination is performed.

In addition, in the above embodiments, the imaging support device according to the present invention is configured by the RIS server 20 and the examination implementer terminal 40. However, each process performed by the RIS server 20 and the examination implementer terminal 40 (particularly the imaging examination process in FIG. 15 and steps S68 to S73 of the system linkage process in FIG. 21 and FIG. 22) may be executed by a single device. Also, each process may be shared and executed by three or more devices.

The programs for executing each process in each device may be stored on a portable recording medium. A carrier wave may also be used as a medium for providing program data via a communication line.
