An example of searching for data will be described.

  First, when an examination list display operation is performed from the operation unit 8, the X-ray diagnostic imaging apparatus 100 starts operation (step S1).

  The system control unit 9 instructs the image display unit 7 to display examination list data. The retrieval unit 72 reads the examination date and the identification information of the subject P from the examination information stored in the image data storage unit 71 for each examination, and outputs the examination list data to the synthesis unit 75. The combining unit 75 outputs the examination list data output from the search unit 72 to the monitor 76. The monitor 76 displays examination list data (step S2).

  FIG. 6 is a diagram illustrating an example of examination list data displayed on the screen of the monitor 76. In the first display area 81 of the screen 80a, the examination list data 84 output from the combining unit 75 is displayed. The second and third display areas 82 and 83 are blank.

  The examination list data 84 is displayed in the “examination date” column in which the date of the examination is displayed, the “name” column in which the name of the subject P in which the examination was conducted is displayed, and the “name” column. The “ID” field in which the ID number of the subject P displayed is displayed, the “birth date” field in which the birthday of the subject P displayed in the “name” field is displayed, and the like.

  Then, the examination date displayed in the columns of “examination date”, “name”, “ID”, “birth date”, etc. from the examination list data 84 displayed in the first display area 81 is 2008. The examination selection operation for selecting, for example, “2008/08/07”, “TT”, “12345678”, “1973/01/01” and the like corresponding to the identification information of the subject P1 on August 7 is operated. When the process is performed from the unit 8, the search unit 72 includes “2008/08/07”, “TT”, “12345678”, and “1973/01 /” among the examination information stored in the image data storage unit 71.

  The image data 92 displayed in the first display area 81 is image data corresponding to, for example, 3D thumbnail data 87 of the 3D thumbnail arrangement data 85 shown in FIG.

  The 3D thumbnail arrangement data 85a displayed in the second display area 82 is different from the 3D thumbnail arrangement data 85 in that the edge of the 3D thumbnail data 87 designated from the operation unit 8 is, for example, highlighted 3D thumbnail data 87a. It is a point that has been replaced.

  The 2D thumbnail data 93 displayed in the third display area 83 is 2D thumbnail data corresponding to, for example, 3D thumbnail data 88 close to the angle of the 3D thumbnail data 87a included in the 3D thumbnail arrangement data 85a.

Thereby, it can be determined whether or not the designated 3D thumbnail data 87 is desired image data.

  Further, 2D thumbnail data of image data close to the shooting angle of the image data corresponding to the specified 3D thumbnail data can be displayed on the monitor 76. This facilitates retrieval of desired image data in the case where there are a plurality of image data with close imaging angles, so that the examination and treatment of the subject P1 can be performed quickly.

  Further, by displaying the 3D thumbnail arrangement data 85a together with the image data 92 on the monitor 76, when the designated 3D thumbnail data 87a is different from the desired image data, other 3D thumbnail data can be quickly designated. it can. Further, by displaying the 2D thumbnail data 93 together with the image data 92 on the monitor 76, the 2D thumbnail data can be quickly specified when the specified 3D thumbnail data 87a is different from the desired image data.

  Here, the image data 92 displayed in the first display area 81 of the screen 80 c is enlarged to the first to third display areas 81 to 83 by the enlargement operation of the first display area 81 from the operation unit 8. Can be displayed. Further, image data corresponding to the designated 2D thumbnail data 93 can be displayed in the first display area 81 by a designation operation for designating the 2D thumbnail data 93 displayed in the third display area 83.

  After “No” in step S4, the 3D thumbnail data generation unit 74 outputs the 3D thumbnail arrangement data identifying the specified 3D thumbnail data in the 3D thumbnail arrangement data 85 to the synthesis unit 75.

  The combining unit 75 generates second combined data from the image data output from the search unit 72 and the 3D thumbnail arrangement data output from the 3D thumbnail data generating unit 74 and outputs the second combined data to the monitor 76. The monitor 76 displays the third combined data output from the combining unit 75 (step S6 in FIG. 5).

This makes it possible to determine whether the image data is desired.

  After step S5 or step S6, the image data 92 displayed in the first display area 81 of the screen 80c of the monitor 76 or the image data 94 displayed in the first display area 81 of the screen 80d is observed, and the operation unit When the search end operation is performed from 8, the system control unit 9 instructs the image display unit 7 to stop, and the X-ray diagnostic imaging apparatus 100 ends the operation (step S7 in FIG. 5).

  According to the embodiment of the present invention described above, the 2D thumbnail data generated from the image data obtained by the examination of the subject P1 is converted into the 3D space corresponding to the imaging angle of the image data corresponding to the 2D thumbnail data. Each 3D thumbnail data 87 to 91 set to an angle can be displayed on the monitor 76. Thereby, the visibility of the shooting angle of the image data corresponding to each 3D thumbnail data 87 to 91 can be improved, and the relationship between the shooting angles of the respective image data can be easily grasped.

  Further, 3D thumbnail arrangement data 85 in which the respective 3D thumbnail data 87 to 91 are arranged on the 3D model 86 can be displayed on the monitor 76. Thereby, the visibility of the imaging angle of each image data with respect to the subject P1 can be improved, and the relationship between the subject P1 and the imaging angle of each image data can be easily grasped.

  Furthermore, 2D thumbnail data 93 of image data close to the shooting angle of the image data 92 corresponding to the designated 3D thumbnail data 87 can be displayed on the monitor 76. Thereby, it is possible to easily search for desired image data when there are a plurality of image data with close photographing angles.

  Furthermore, by displaying the 3D thumbnail arrangement data 85a together with the image data 92 on the monitor 76, when the specified 3D thumbnail data 87 is different from the desired image data, other 3D thumbnail data can be specified quickly. Can do. Further, by displaying the 2D thumbnail data 93 together with the image data 92 on the monitor 76, when the designated 3D thumbnail data 87 is different from the desired image data, the 2D thumbnail data can be designated quickly.

  As described above, it becomes easy to search for desired image data, and it is possible to quickly examine and treat the subject P1.
