[Preliminary study of radiological image transmission with B-ISDN]

We evaluated the utility of image transmission using broad band ISDN (B-ISDN). The B-ISDN network links Tohoku University Hospital (TUH), interfaced with CDDI, and Tohoku University Department of Technology, interfaced with FDDI (including Tohoku University Computer Center interfaced with Ethernet), at 10km distance interfaced to a Unix workstation. Voluminous radiographic images like MRI 3-D images of the pelvic organs digitized at 5-20 megabytes were transmitted at mean data rates of 1.03Mbps (CDDI-Ethernet) and 30.1Mbps (FDDI-CDDI) with no image distortion. Initially the image data are transmitted to the Computer Center & Department of Technology, then processed and relayed to TUH. B-ISDN can provide fast, accurate image transmission.
