The operation input unit 26 includes input devices such as a keyboard and a mouse. The display unit 28 is a display device such as a CRT, a plasma display, or a liquid crystal display. The image memory 22 stores the image data input via the A / D converter 21. The filtering unit 23 performs image correction processing such as high-frequency enhancement filtering on the image data. The affine transformation unit 24 performs enlargement processing and movement processing on the image data. The LUT 25 is a table for performing gradation conversion on image data.

  The three-dimensional model memory 31 stores a three-dimensional model that represents each part constituting the entire body in a three-dimensional shape. In this embodiment, for example, a standard three-dimensional model of a blood vessel is stored. The blood vessel name database 32 stores blood vessel names or abbreviations corresponding to a plurality of blood vessel portions of the model. The technique list database 33 stores data representing a technique list corresponding to each of a plurality of blood vessel portions. The procedure list is a list of procedure names and procedure states.

  The three-dimensional model display unit 34 reads a specific model selected from a plurality of models according to a user instruction from the three-dimensional model memory 31 and displays it on the display unit 28.

  The comment creation support unit 35 reads the name corresponding to the blood vessel portion designated by the user on the model displayed on the display unit 28 from the blood vessel name database 32, and inserts the read name into the examination comment. Further, a procedure list corresponding to the designated blood vessel portion is read from the procedure list database 33 and displayed, and data representing a procedure selected by the user from the displayed procedure list is inserted into the comment.

Next, the operation of the X-ray diagnostic apparatus configured as described above will be described.
When the examination is started by the X-ray diagnostic apparatus, examination information such as a patient name and a patient ID is input. The examination information may be registered with ONLINE via HIS (Hospital Information System), RIS (Radiology Information System), or may be manually entered into the diagnostic system. Among them, there is a selection of an imaging program. For example, they are set for each imaging region such as a cardiac examination program, a head examination program, and an abdominal examination program.

  The X-ray diagnostic apparatus starts an inspection when information necessary for the inspection is input. When the examination is started, the three-dimensional model display unit 34 reads the standard blood vessel three-dimensional model from the three-dimensional model memory 31 and displays it on the display unit 28. FIG. 3 is a display example of the standard blood vessel three-dimensional model displayed by the three-dimensional model display unit 34. As shown in FIG. 3, the three-dimensional model display unit 34 first displays a three-dimensional model of the entire body, and the operator designates an arbitrary part such as the head, heart, abdomen, and lower limbs in the displayed model. To do. For example, when the heart is designated here, the arterial system is displayed as aorta, pulmonary artery, coronary artery by default. When switching to vein display, vena cava and pulmonary veins are displayed. Here, when the coronary artery is selected, the aorta and the pulmonary artery are not displayed, and only the coronary artery is displayed on the display unit 28.

  As described above, the standard three-dimensional model has a hierarchical structure, and a target blood vessel can be displayed by selecting a lower hierarchy. The hierarchical structure can be selected by jumping from the heart to the right coronary artery immediately, or leaving the left and right coronary arteries displayed without specifying the left and right. When the examination protocol is configured for each imaging region, a three-dimensional model of the imaging region (for example, the heart) can be automatically displayed by selecting the examination protocol.

  When the C-arm 160 is moved in an appropriate shooting direction, the three-dimensional model display unit 34 automatically rotates the three-dimensional model displayed on the display unit 28 in accordance with the image shooting direction. This rotation has an automatic mode and a manual mode, and both can be changed. In the manual mode, the 3D model display unit 34 rotates the 3D model according to the operation information input from the operation input unit 26. For example, when the operator drags the mouse on the three-dimensional model and moves it left and right, the three-dimensional model rotates left and right, and when the operator moves the mouse up and down, the three-dimensional model rotates up and down.

  Next, the operator clicks the target portion of the blood vessel with the mouse before taking the blood vessel during the examination. The comment creation support unit 35 identifies the blood vessel that has been left-clicked, and refers to the blood vessel name database 32 and inserts the blood vessel name or abbreviation of the blood vessel into the examination comment of the next photographed image. Here, as a result, the “left coronary artery” is inserted into the examination comment.

  At this time, if the user does not left-click but right-clicks, the comment creation support unit 35 refers to the technique list database 33 and displays a pull-down menu with selections of the name of the specific technique corresponding to that part and the state of the technique. To do. For example, as shown in FIG. 4, for example, “Stenting”, “Pre-Senting”, “Post-Senting”, and the like are displayed as options. Here, when the operator selects “Pre-Senting”, the comment creation support unit 35 inserts the selected technique information together with the name of the designated portion into the examination comment. As a result, “left coronary artery Pre-Stenting” is inserted into the examination comment.

  When moving to imaging of a different blood vessel, the model of the entire cardiovascular in the upper hierarchy can be displayed by pressing the upper right arrow in FIG. 4 while displaying the coronary artery. Also, as shown in FIG. 5, a hierarchical tree may be displayed, and the target part may be uniquely displayed from the tree.

  As described above, in the above-described embodiment, the blood vessel three-dimensional model data corresponding to a plurality of parts of the subject is stored in the three-dimensional model memory 31, and the plurality of names of data corresponding to the plurality of blood vessel portions of the model are stored in the blood vessel. Stored in the name database 32. The three-dimensional model display unit 34 displays a specific model selected from a plurality of models according to a user instruction. The comment creation support unit 35 reads the name corresponding to the blood vessel portion designated by the user on the displayed model from the blood vessel name database 32, and inserts the read name into the examination comment.

  With this configuration, the operator simply specifies the blood vessel to be examined on the three-dimensional model displayed on the screen, and an accurate blood vessel name is inserted into the examination comment. Further, a procedure list corresponding to the designated blood vessel is displayed, and information indicating the selected procedure is inserted into the comment together with the blood vessel name. Therefore, according to the above-described embodiment, it is possible to prevent a mistake in inputting an inspection comment and to input a comment easily and accurately.
