Integrated diagnostic support system (IDSS) is a system which manages not only text data but also medical images on the central database and provides doctors most medical care information on a single workstation. IDSS consists of host database management, a gateway, and workstation. Medical images are sent to the host from medical imaging modalities through a gateway program and are saved in the database. When images are required at workstations, those images are sent from the host to the workstation and saved in the workstation database. The workstation has functions to display images which are in local disks. Doctors can select single or multiple images to display by mouse operation. There are three database layers such as a host cash, a long term storage, and a local workstation. Medical images which are referred to frequently are held in the host cash but moved to the long term storage at a certain point. In order to see medical images on the workstation, the images have to be loaded into the local database by the host applications or a doctor's operations.
