SUMMARY OF THE INVENTION The above-mentioned prior art is based on ID
In B, the IWS sequentially performs data communication until it obtains the location information of the desired medical image from the database registered by associating the search keyword of the medical image input to the IWS with the location storage medium of the medical image of MID. For the processing of confirming the end in (1), there is a problem that the data communication of PACS is restricted because the processing occupies the processing time network.

The present invention has been made in view of the above problems, and an object thereof is to reduce the frequency of data communication between the IWS and the IDB to improve the efficiency of data communication of the network in PACS. Is.

[0007]

[Means for Solving the Problems] The above object is to provide an IWS having an operation console for inputting a search keyword for a medical image and an image display device for displaying a medical image, and a search keyword for a medical image input on the operation console of the IWS. And an IDB for registering a medical image location storage medium as a database in association with each other, an MID having a medical image location storage medium registered in the IDB, the IWS, and the IDB.
In the medical image storage / transmission system, the communication management device comprises: a network for performing data communication between the MID and the MID; and a communication management device for managing the data communication in the IWS, the IDB, and the MID. Means for setting the expected data communication end time, means for measuring the data communication end time, and means for constantly comparing the data end time of the measuring means with the expected data communication end time of the setting means , The means for notifying the IWS, the IDB, and the MID that the data end time of the comparison means has exceeded the scheduled data communication end time, and the I which has received the notification of the notifying means.
This is achieved by interrupting the data communication performed by WS, the IDB, and the MID, and discarding the interrupted data of the data communication.

[0008]

In the PACS, the means for setting the data communication end scheduled time in the communication management device, the means for measuring the data communication end time, the data end time of the measuring means and the data communication end of the setting means Means for constantly comparing the scheduled time and the IWS, the IDB, and the MID having the communication management device that the data end time of the comparing means exceeds the data communication end scheduled time.
The IWS, the IDB, and the MID, which have received the notification, interrupt the data communication and discard the data of the interrupted data communication. It is not necessary to perform the unfinished search communication to the IDB, the process of determining whether the unfinished search is performed in the IDB, and the unfinished search response communication from the IDB to the IWS until the search is completed. , M
When the communication time set in advance in the ID communication management device elapses, the communication data is discarded, so that the frequency of data communication can be reduced.

[0009]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of a PACS communication management apparatus of the present invention, and FIG. 2 is a flowchart of the PACS of the present invention.
