The comparison target item file 63 is a file that stores item data indicating items (comparison target items) to be compared between the order information DT5 and the incidental information DT2, and is preset by initial setting or the like. As shown in FIG. 3, the comparison target item file 63 stores item data such as a patient ID, a name (Roman characters, Kanji characters, Kana), a reception number, and an examination ID.

  The CPU 10 extracts the data of the comparison target item indicated by the item data stored in the comparison target item file 63 from the order information DT5 and the accompanying information DT2. The extracted comparison target item data is stored in the inconsistency determination table 52. As shown in FIG. 4, the inconsistency determination table 52 is a data table that stores incidental information, order information, and inconsistency flags for each comparison target item in association with each other.

  The inconsistency flag is a flag indicating whether or not they match as a result of comparing the incidental information and the order information, and is set to OFF when they match and ON when they do not match. In FIG. 4, since the “reception number” of the item to be compared does not match, the mismatch flag is set to ON.

  The user can check the inconsistency flag of the inconsistency determination table 52 on the inconsistency correction screen 110 shown in FIG. The CPU 10 displays a list of items to be compared, supplementary information, order information, and inconsistency flag in the inconsistency determination table 52 on the inconsistency correction screen 110.

Perform the series split operation to move to. When detecting the series dividing operation, the CPU 10 divides the series by updating the series information DT22 of the designated medical image data DT1 with new series information DT22.

  The image inspection history button 105 is a button for displaying an image inspection history screen 140 that displays data contents of the image inspection history table 64. FIG. 5 shows an example of the data structure of the image inspection history table 64. According to FIG. 5, the image inspection history table 64 stores date / time information, examination ID, series ID, image number, and history data in association with each other. The history data is data indicating a history of data processing performed by the imaging device 1, and includes operation data indicating an imaging operation by the user and determination data indicating a determination result of success or failure of transmission.

  When the user performs image inspection and detects the operation of the image acquisition, the CPU 10 acquires the current date and time, the examination ID, the series ID, and the image number of the medical image data DT1 for which the image inspection has been performed. The image data is stored in the imaging history table 64 in association with operation data (history data) indicating the operation.

  In addition, when the medical image data DT1 stored in the transfer image table 53 is transferred to the PACS2, the current date and time, the examination ID, the series ID, and the image number of the transferred medical image data DT1 are acquired, and the determination data The image data is stored in the imaging history table 64 in association with (history data).

  The determination data is data indicating success or failure of transmission of the medical image data DT1, and is set according to whether or not all of the medical image data DT1 transmitted from the imaging apparatus 1 has been received by the PACS2. For example, when the medical image data DT1 is transmitted to the PACS2, the CPU 10 transmits in advance size data indicating the data amount of the medical image data DT1 to be transmitted to the server 3 of the PACS2.

  The server 3 determines whether or not all the medical image data DT1 has been received based on the number and the data capacity of the medical image data DT1 received from the imaging apparatus 1 and the size data received in advance. At this time, when all the medical image data DT1 is received, a reception success signal indicating successful reception is transmitted to the imaging device 1, and when all the medical image data DT1 is not received, reception failure is indicated. A reception failure signal is transmitted to the imaging device 1.

  The CPU 10 of the imaging device 1 determines whether the transmission of the medical image data DT1 is successful based on the reception success signal or the reception failure signal transmitted from the server 3. It should be noted that a known technique can be appropriately employed as a method for determining the success or failure of transmission of the medical image data DT1.

  When the CPU 10 detects designation of the image detection history button 105 on the image detection list screen 100 by the user, the CPU 10 reads the image detection history table 64 and causes the display unit 30 to display an image detection history screen 140 as shown in FIG.

And when it determines with not having received all the medical images (step C2; No), after transmitting a reception failure signal to the image examination apparatus 1, it transfers a process to step C1.

  If it is determined that all medical images have been received (step C2; Yes), a reception success signal is transmitted to the image inspection device 1 and the received medical image data DT1 is stored in the image management DB (step C5). ).

  On the imaging device 1 side, after the transmission of the medical image data DT1, the CPU 10 determines the success or failure of the transmission of the medical image data DT1 based on the reception success signal or the reception failure transmitted from the server 3 (step D12). . At this time, if the reception success signal is received and it is determined that the transmission of the medical image data DT1 is successful (step D12; Yes), the determination data indicating the successful transmission is stored in the imaging history table 64 ( Step D13).

  If the reception failure signal is received and it is determined that the transmission of the medical image data DT1 has failed (Step D12; No), the determination data indicating the transmission failure is stored in the imaging history table 64 (Step S12). D14).

  Next, details of the image inspection process in step D6 will be described. The CPU 10 reads the medical image data DT1 from the examination image DB 62, acquires the auxiliary information DT2 from the medical image data DT1 (step E1), and orders the order information DT5 having the same examination ID as the auxiliary information DT2. Read from the DB 61 (step E2).

  Then, after extracting the data of the comparison target item from the auxiliary information DT2 and the order information DT5 read in steps E1 and E2, and storing the data in the inconsistency determination table 52 (step E3), the data of the comparison target item is respectively In comparison, ON / OFF of the inconsistency flag is set and stored in the inconsistency determination table 52 (step E4).

  Based on the inconsistency flag stored in the inconsistency determination table 52, the CPU 10 determines whether or not there is a comparison target item of the inconsistent incidental information DT2 (step E5). At this time, if it is determined that there is an inconsistent comparison target item (step E5; Yes), inconsistency notification information 106 indicating that there is a mismatch such as “NG” in FIG. (Step).

  If it is determined that there is no mismatched item to be compared (step E5; No), the standard inspection list screen 100 that does not include the mismatch notification information 106 is displayed on the display unit 30 (step E8).

  When the CPU 10 detects that the inconsistency correction button 104 has been pressed after displaying the inspection list screen 100 including the inconsistency notification information 106 in step E6, based on an operation signal from the input unit 20. (Step E7: Yes), the inconsistency determination table 52 corresponding to the medical image data DT1 selected on the imaging list screen 100 is read, and the inconsistency correction screen 110 is displayed based on the inconsistency determination table 52. It is displayed on the part 30 (step E9).

  Then, the medical image data DT1 selected on the imaging list screen 100 is read from the imaging image DB 62, and a copy (duplication) of the medical image data DT1 is generated and stored in the imaging image table 51 ( Step E10).

  The CPU 10 performs processing in response to pressing of the partial rewrite button 111, the batch rewrite button 112, and the cancel button 113 on the inconsistency correction screen 110. Specifically, when pressing of the partial rewrite button 111 is detected according to an operation signal from the input unit 20 (step E11; Yes), the inconsistency determination table 52 corresponding to the pressed partial rewrite button 111 is displayed. Are temporarily rewritten with the associated order information (step E12).

  If it is detected that the batch rewrite button 112 has been pressed (step E13; Yes), all supplementary information in the inconsistency determination table 52 is provisionally rewritten with the corresponding order information (step E14).

  If it is detected that the cancel button 113 has been pressed (step E15; Yes), the supplementary information DT2 provisionally rewritten in step E12 or E14 is stored in the original medical image data DT1 stored in the examination image DB 62. By updating with the incidental information DT2, the temporarily rewritten information is reset (step E16), and the process proceeds to step E22.

  The CPU 10 determines whether or not the OK button 114 has been pressed (step E17) after the processing of steps E12 and E14 or when it is determined in step E15 that the cancel button 113 has not been pressed (step E15; No). At this time, when it is detected that the OK button 114 is pressed (step E17; Yes), the contents of the rewriting of the incidental information DT2 processed in step E12 or E14 are stored as history data in the imaging history table 64. (Step E18).

  Then, the supplementary information DT2 of the medical image data DT1 in the image-in-view image table 51 is rewritten and updated based on the rewriting contents of steps E12 and E14 (step E19), and the information corresponding to the rewritten comparison target item is updated. The inconsistency flag in the consistency determination table 52 is changed to OFF and set (step E20).

  For example, in FIG. When the inconsistency correction button 104 is pressed with 10 pieces of medical image data DT101 selected, an inconsistency correction screen 110 as shown in FIG. 11 is displayed. When the partial rewrite button 111 corresponding to “reception number” is pressed, the reception number “11111111” in the inconsistency determination table 52 of FIG. 4 is provisionally rewritten with the reception number “1050829003”.

  Further, when the OK button 114 is pressed, the provisional rewriting is confirmed and the incidental information DT2 of the medical image data DT1 stored in the image-in-image table 51 is updated. At this time, the inconsistency flag “ON” of the receipt number in the inconsistency determination table 52 is changed to “OFF”. Further, as in the image examination history table 64 of FIG. 5, operation data (history data) indicating that the reception number has been changed is stored together with the examination ID, series ID, and image number for identifying the medical image data DT1.

  The CPU 10 determines whether or not the inconsistency flag “ON” is stored in the inconsistency determination table 52 (step E21), and if it is stored (step E21; Yes), the process proceeds to step E9. And the inconsistency correction screen 110 is displayed on the display unit 30 again. Further, when it is determined that the inconsistency flag “ON” is not stored (step E21; No), after the process of step E16, the process proceeds to the process of step E22 and the inspection list screen 100 is displayed on the display unit 30. It is displayed (step E22).

  Next, when pressing of the image confirmation button 103 is detected based on an operation signal from the input unit 20 (step E23; Yes), the image confirmation screen 120 is displayed. The CPU 10 acquires the examination ID of the medical image data DT1 selected on the examination list screen 100, and reads out the medical image data DT1 having the examination ID from the examination image DB 62. Then, an image confirmation screen 120 as shown in FIG. 12 for displaying a list of the medical image data DT1 for each read series (for example, thumbnail display) is displayed on the display unit 30 (step E24).

  Further, the CPU 10 generates a copy of the medical image data DT1 displayed on the image confirmation screen 120 and stores it in the image-in-image table 51 (step E25). Then, processing corresponding to pressing of each button on the image confirmation screen 120 is performed.

  Specifically, when pressing of the OK button 122 corresponding to each medical image data DT1 is detected (step E26; Yes), the medical image data DT1 corresponding to the OK button 122 is stored in the transfer image table 53. (Step E27).

  When the pressing of the image processing button 124 is detected (step E30; Yes), the image processing conditions (for example, change in contrast ratio density) input in response to the pressing of the image processing button 124 are acquired. Then, the medical image data DT1 being displayed is subjected to image processing and updated (step E32).

  If it is detected that the supplementary information correction button 127 shown in FIG. 12 has been pressed (step E33; Yes), the supplementary information input in the supplementary information input area 128 is acquired, and the image table during imaging The auxiliary information DT2 of the medical image data DT1 in 51 is updated (step E35).

  When it is detected that the series division button 125 is pressed (step E36; Yes), the medical image data DT1 being displayed on the image confirmation screen 120 is displayed on the series division screen 130 for each series ( Step E37). Then, for each of the displayed series, a new series ID is set in the incidental information DT2 according to the user's series dividing operation on the medical image data DT1, and the medical image data DT1 in the image-in-image table 51 is updated ( Step E38).

  After the processing in steps E27, E32, E35, and E38, the CPU 10 stores the contents of the operation performed in each step as history data in the imaging history table 64 (step E27). Then, the process proceeds to step E24 and the processes of steps E24 to E28 are repeated until it is detected that the test end button 126 is pressed. In this way, the processing result of the image inspection process of FIG. 6 and the transmission of the medical image data DT1 is stored in the image inspection history table 64.

  In the flowchart of FIG. 6, when the pressing of the imaging history button 105 is detected (step D <b> 1; Yes), the CPU 10 reads the imaging history table 64 and displays the imaging history screen 140 as shown in FIG. 14 on the display unit 30. It is displayed (step D8). Then, it is determined whether or not the pressing of the re-examination button 143 is detected (step D9). When the pressing of the re-examination button 143 is detected (step D9; Yes), the selection button 142 is pressed. Medical image data DT1 subjected to image inspection based on the history data is generated and stored in the transfer image table 53.

  For example, as shown in FIG. 14, when the selection button 142 corresponding to the imaging result “transfer failure” is pressed, the medical image data DT1 having the examination ID “11111111” and the series ID “2222222” is selected. Data processing that is read out from the examination image DB 62 and changes the reception number “11111111” to “1050829003” based on the examination history table 64 for the medical image data DT1, a series of medical image data DT1 with the image number “2” Data processing for changing the ID from '222222222' to '333333333' is performed and stored in the transfer image table 53.

  As described above, according to the present embodiment, the history of data processing performed by the user on the medical image data DT1 and the history of success or failure of transmission of the medical image data DT1 are associated with the identification information of the medical image data DT1. Then, the data is stored in the image inspection history table 64, and data processing of the image inspection operation performed by the user in the past is performed based on the image inspection history table 64. For this reason, the user can easily cause the imaging device 1 to perform the imaging operation without repeating the imaging operation performed in the past and generate the medical image data DT1 subjected to the imaging. Can be made. Therefore, it is possible to realize an imaging device 1 that is easy to use and can reuse the imaging operations performed in the past.

  In the above-described embodiment, it has been described that the history data of the user's imaging is stored in the imaging device 1, but this history may be stored on the PACS 2 side. For example, the server 3 or the client 4 detects the user's image inspection operation on the medical image data DT1, and stores the image history data in an accumulated manner. Based on the history data, the user's image inspection operation is reproduced.

  At this time, for example, the server 3 or the client 4 transmits the medical image data DT1 already imaged to the electronic medical chart system or the HIS, stores the determination data indicating the success or failure of the transmission in the image detection history table, and described above. The history may be reproduced as in the embodiment.

  Further, although it has been described that the medical image data DT1 subjected to the processing based on the imaging history table 64 in step D10 is stored in the transfer image table 53 and the processing is shifted to step D7, for example, the image confirmation screen 120 When the selection button 142 specified above indicates transfer failure history data, the processing may be shifted from step D10 to step D11, and the medical image data DT1 may be automatically transmitted to the server 3.
