When the candidate output function 115 is executed, the signal processing circuit 11 outputs the calculated destination data center candidate to the communication terminal 40. Specifically, the signal processing circuit 11 generates a display image in which destination data center candidates are arranged in order of priority (step S518). The signal processing circuit 11 converts the generated display image into an image signal. The signal processing circuit 11 transmits the image signal to the communication terminal 40 via the IP network (step S519).

  Note that the signal processing circuit 11 does not necessarily generate a display image. The signal processing circuit 11 may transmit, to the communication terminal 40, information regarding the priority of the destination data center candidate instead of the image signal. At this time, the signal processing circuit of the communication terminal 40 has an image generation function, and generates a display image in which destination data center candidates are arranged in order of priority based on information transmitted from the communication terminal 40.

  The communication terminal 40 receives an image signal transmitted from the medical information processing apparatus 10. The signal processing circuit of the communication terminal 40 decodes the received image signal. The communication terminal 40 displays the decoded display image on the display circuit (step S520). FIG. 14 is a schematic diagram illustrating an example of a display screen displayed on the display circuit of the communication terminal 40 according to the present embodiment. According to FIG. 14, the data centers that are medical information destination candidates of examination ID: 00000001 are arranged and displayed in order of priority. A data center with a higher priority represents a data center suitable for movement. Moreover, evaluation for each viewpoint is displayed for each data center.

  FIG. 15 is a schematic diagram illustrating another example of the display screen displayed on the display circuit of the communication terminal 40 according to the present embodiment. According to FIG. 15, the data centers that are medical information destination candidates of examination ID: 00000002 are arranged and displayed in order of priority. Moreover, evaluation for each viewpoint is displayed for each data center.

  The user selects one of the data centers 20-1 to 20-3 displayed on the display circuit of the communication terminal 40 via the input interface circuit. Specifically, the user selects any of the data centers 20-1 to 20-3 displayed as the movement destination candidates for the medical information with the examination ID: 00000001 via the input interface circuit. Further, the user selects any of the data centers 20-1 to 20-3 displayed as the movement destination candidates for the medical information with the examination ID: 00000002 via the input interface circuit.

  When any of the displayed data centers 20-1 to 20-3 is selected, the signal processing circuit of the communication terminal 40 generates a selection signal that can identify the selected data center. The communication terminal 40 transmits the generated selection signal to the medical information processing apparatus 10 via the IP network (step S521).

  The medical information processing apparatus 10 receives the selection signal transmitted from the communication terminal 40. When receiving the selection signal, the signal processing circuit 11 of the medical information processing apparatus 10 executes a DC determination function. When the DC determination function is executed, the signal processing circuit 221 determines the data center specified by the selection signal as the transfer destination of the medical information (step S522).

  Note that FIG. 5 illustrates an example in which the signal processing circuit 11 starts processing using a desired signal transmitted from the communication terminal 40 as a trigger. However, it is not limited to this. The signal processing circuit 11 may have a position information acquisition function by executing a processing program stored in the storage circuit 12. When the position information acquisition function is executed, the signal processing circuit 11 generates a position information request signal at a predetermined timing, for example, at a preset period or at a preset time. The position information request signal is transmitted to a specific user stored in the user information 121.

  When receiving the position information request signal, the communication terminal 40 acquires the current position information of the user by the position acquisition circuit. The communication terminal 40 transmits the acquired position information to the medical information processing apparatus 10 via the IP network. When receiving the position information via the IP network, the signal processing circuit 11 of the medical information processing apparatus 10 associates the received position information with the user ID, and stores them in the storage circuit 12 as the user position information 122. When the user position information 122 is stored, the signal processing circuit 11 executes the processing after step S54 shown in FIG. Thereby, the medical information processing apparatus 10 can present a data center suitable for use to the user in accordance with the movement of the user.

  Further, in FIG. 5A, the case where there is a single user has been described as an example. However, it is not limited to this. There may be a plurality of users. The signal processing circuit 11 calculates medical information destination candidates for a plurality of communication terminals that have transmitted the desired signal. At this time, the signal processing circuit 11 may calculate medical information destination candidates according to the order in which the desired signals are received. Further, the signal processing circuit 11 may calculate medical information destination candidates in order from the user with the highest priority among the plurality of users who transmitted the desired signal. At this time, the user information 121 includes information indicating the priority of the user.

  In FIG. 5A, the case where the name: doctor Ichiro is read from the user information 121 based on the user ID: 00001 in step S54 has been described as an example. However, it is not limited to this. Based on the user ID: 00001, the signal processing circuit 11 may read information other than the name, such as job title, specialty, or institution, from the user information 121. The signal processing circuit 11 generates a meta information request signal for requesting meta information about the read information.

  Further, FIG. 5 illustrates an example in which the destination data center of medical information for an examination handled by Dr. Ichiro is determined. However, it is not limited to this. The signal processing circuit 11 may display medical information to the user and allow the user to select medical information about an examination that needs to be moved. For example, the signal processing circuit 11 displays the meta information 125 stored in the storage circuit 12 on the communication terminal 40 in step S513 of FIG. 5A. The user selects medical information about a test that needs to be moved from medical information about a plurality of tests displayed on the display circuit of the communication terminal 40. When the medical information about the examination that needs to be moved is selected, the signal processing circuit 11 calculates the data center of the movement destination candidate for the selected medical information in step S517. As a result, the signal processing circuit 11 can calculate the movement destination only for the medical information that is determined to be moved by the user.

  Further, the signal processing circuit 11 reports whether or not to analyze the medical image on the data center when selecting the medical information about the examination that needs to be moved, or refers to the medical image on the data center and reports it. It may be possible for the user to input whether or not to create. At this time, scenes for image analysis or report creation are registered in the weighting information 127 stored in the storage circuit 12. In the weighting information 127, the viewpoint of this scene may include, for example, the presence or absence of a predetermined analysis application. The signal processing circuit 11 reads the weighting factor for the scene: “image analysis” or “report creation” from the weighting information 127 and calculates the data center of the destination candidate using the read weighting factor. As a result, the priority of the data center on which the desired analysis application is mounted is set high.

  FIG. 16 is a diagram illustrating a processing procedure in the medical information storage system when moving medical information between data centers. In the example of FIG. 16, a case will be described in which the data center 20-1 is selected as the transfer destination of the medical information with the examination ID: 00000001 in step S520 of FIG.

  In FIG. 16A, when the data center 20-1 is determined as the movement destination (step S522), the signal processing circuit 11 of the medical information processing apparatus 10 executes the movement control function 117. When the movement control function 117 is executed, the signal processing circuit 11 generates a movement instruction signal. The movement instruction signal is a signal for instructing movement of the medical information of examination ID: 00000001 to the data center 20-1. The signal processing circuit 11 transmits the generated movement instruction signal to the data center 20-2 storing the medical information of the examination ID: 00000001 and the data center 20-1 determined as the movement destination via the IP network. (Step S161).

  The proxy server 21 provided in the data center 20-2 receives the movement instruction signal via the IP network. When the signal processing circuit 211 of the proxy server 21 receives the movement instruction signal, the signal processing circuit 211 executes the movement control function 2112. When the movement control function 2112 is executed, the signal processing circuit 211 generates a second readout signal instructing readout of the medical information with the examination ID: 00000001. The signal processing circuit 211 transmits the generated second read signal to the storage servers 22-1 to 22-3 provided in the data center 20-2 via the LAN (step S162).

  When the signal processing circuit 221 of the storage server 22-1 receives the second read signal via the LAN, the signal processing circuit 221 executes the read control function 2211. When the read control function 2211 is executed, the signal processing circuit 221 reads the medical information of the examination ID: 00000001 stored in the storage circuit 222 (step S163). When the signal processing circuit 221 reads the medical information of the examination ID: 00000001, the signal processing circuit 221 transmits the read medical information of the examination ID: 00000001 to the proxy server 21 via the LAN (step S164).

  The storage servers 22-2 and 22-3 that have received the second read signal also perform the processes of step S163 and step S164. As a result, the medical information of the examination ID: 00000001 is also transmitted to the proxy server 21 from the storage servers 22-2 and 22-3.

  The proxy server 21 provided in the data center 20-2 receives the medical information of the examination ID: 00000001 transmitted from the storage servers 22-1 to 22-3. The signal processing circuit 211 of the proxy server 21 transmits the received medical information of the examination ID: 00000001 to the data center 20-1 via the IP network (step S165).

  In FIG. 16B, the proxy server 21 provided in the data center 20-1 receives a movement instruction signal and medical information of examination ID: 00000001 via the IP network. When the signal processing circuit 211 of the proxy server 21 receives the movement instruction signal and the medical information of the examination ID: 00000001, it executes the write control function 2116. When the writing control function 2116 is executed, the signal processing circuit 211 generates a writing signal instructing writing of medical information of examination ID: 00000001. The signal processing circuit 211 transmits the generated write signal to the storage servers 22-1 to 22-3 provided in the data center 20-1 via the LAN (step S166).

  When the signal processing circuit 221 of the storage server 22-1 receives the write signal via the LAN, the signal processing circuit 221 executes the write control function 2213. When the write control function 2213 is executed, the signal processing circuit 221 writes the medical information of the examination ID: 00000001 into the storage circuit 222 (Step S167). When the writing of the medical information with the examination ID: 00000001 is completed, the signal processing circuit 221 notifies the proxy server 21 that the writing has been completed via the LAN (step S168).

  The storage servers 22-2 and 22-3 that have received the write signal also perform the processing of step S167 and step S168. As a result, the medical information of the examination ID: 00000001 is also written in the storage circuit 222 of the storage servers 22-2 and 22-3.

  When the proxy server 21 provided in the data center 20-1 receives a notification of writing completion from the storage servers 22-1 to 22-3, the communication terminal 40 indicates that the movement of the medical information of the examination ID: 00000001 is completed. (Step S169). As a notification method at this time, an arbitrary method such as e-mail can be used.

  In FIG. 16A, when notified of the completion of movement, the communication terminal 40 displays that fact on the display circuit (step S1610). Specifically, the user opens an e-mail distributed from the data center 20-1 that is the destination of medical information. When the e-mail is opened, the communication terminal 40 displays on the display circuit that the movement has been completed.

  In addition, in FIG. 16, the case where the completion of movement was notified from the data center 20-1 which is a movement destination of medical information to the communication terminal 40 was demonstrated to the example. However, it is not limited to this. The notification of movement completion may be notified to the medical information processing apparatus 10. When receiving the notification of movement completion from the data center 20-1, the medical information processing apparatus 10 transmits to the communication terminal 40 that the movement has been completed.

  5 and 16, the case has been described as an example where the destination data center of medical information for the examination handled by Dr. Ichiro is determined, and the medical information is moved to the determined data center. However, it is not limited to this. The signal processing circuit 11 may accept designation from the user when calculating the data center of the movement destination candidate for the medical information in step S517. For example, in step S517, the signal processing circuit 11 determines whether or not to analyze a medical image on the data center, whether or not to create a report with reference to the medical image on the data center, and how much time it takes to create the report. You may make it receive the analysis application which wants to perform, and the date (schedule) which starts report preparation. The signal processing circuit 11 determines the destination data center with priority over other medical information so that the movement of the medical information to the data center is completed at the input date and time. Then, the signal processing circuit 11 moves the medical information to the determined data center so that the movement of the medical information to the data center is completed at the input date and time. As a result, the signal processing circuit 11 moves the medical information to a predetermined data center so that a report can be created at the input date and time.
