A system to create and review reports enables interactive manipulation of the displaying of two-dimensional and three-dimensional images associated with image diagnosis reports, at user terminals connected to a medium- or low-speed network. High-speed image processing devices are set up near the network of a PACS server which archives and transmits medical image data, and parameter sets are attached which serve to recreate reference images in diagnosis reports. When users at a requesting department review the reports at user terminals, parameter sets are added to the reports and transmitted to image processing devices. The image processing devices obtain image data from the PACS server based on these parameter sets. Image processing is performed, and the image data is then sent to user terminals.
