[Networks for image communication. Current status]

Networks for the transport of digital images are key components of PACS systems. In order to create a platform for the selection of appropriate network technology, first the quantitative requirements for image data communication in a PACS system are analyzed. State-of-the-art local area networks as well as developments in progress are mentioned, and their performance is discussed with respect to the PACS requirements. Furthermore, the linkage of PACS systems and hospital or radiology information systems is discussed. Finally, a scenario is outlined for extra-mural applications of medical image communication.
