Abstract

High speed data processing devices are set up near a PACS server network which stores medical image data. Devices for preparation of electronic medical reports, attached to electronic medical reports image processing parameters together with image data information, are used during an image diagnosis. Terminal devices for browsing electronic medical reports use information attached to electronic medical report and image processing parameters are sent with information for acquisition of image data to data processing devices near a PACS server in which this image data is stored. The data processing devices acquire image data based on this information with the parameters, image processing is performed and the created images are sent to terminal devices. In addition, the acquisition and displaying of related information is also performed in the same manner. This enables processing and display interactively of images and information related to electronic medical records at a terminal device.
