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.
我们评估了使用宽带综合业务数字网（B-ISDN）进行图像传输的效用。B-ISDN网络连接了东北大学医院（TUH）（与CDDI接口）和东北大学技术系（与FDDI接口，包括与以太网接口的东北大学计算机中心），在10公里的距离处与一台Unix工作站相连。像骨盆器官的MRI三维图像这样数字化后大小为5 - 20兆字节的大量射线图像，以平均数据速率1.03Mbps（CDDI - 以太网）和30.1Mbps（FDDI - CDDI）进行传输，且没有图像失真。最初图像数据被传输到计算机中心和技术系，然后进行处理并中继到东北大学医院。B-ISDN能够提供快速、准确的图像传输。
