Abstract
ImNet/2 is a fiber-optic local area network which was developed for high speed image communication in Picture Archiving and Communication Systems (PACS). ImNet/2 is optimized for the transmission of large data files. The topology of the network is multistar i. e. an arbitrary tree structure of stars. This topology allows multiple transmissions to proceed simultaneously. Therefore the overall throughput of ImNet/2 can be a multiple of the data rate per link.
ImNet/2 is constructed in accordance with the ISO/OSI reference model. For the physical layer the MIC connector is used, which is also standardized for FDDI. Up to layer 3, all protocols are handled by hardware or firmware. At layer 4 a special high speed protocol makes the full network speed available on top of the network-specific OSI layers. Layer 4 allows for several different network-independent protocols to be implemented e.g. DICOM, ACR-NEMA or MEDICOM. Interfaces are available for VMEbus (UNIX, OS/9), ISAbus (UNIX, OS/2, MS-DOS) and SCSI II (under development).
ImNet/2 is commercially available and is currently being installed at several hospitals in Scandinavia. At the Klinikum in Aachen, Germany, the construction of a prototyp network is supported by the AIM project EURIPACS.
