Paper Abstract

This paper seeks to describe work in progress towards the development of a very-high-speed (80 - 200 Mbits/sec) Local Area Network (LAN) for the support of a distributed image processing system. The current practice in most medical, scientific and industrial image acquisition and processing equipment is to use complete, stand-alone image processors dedicated to a particular application. Such a system is not very expandable or flexible and is not cost-effective. A better approach would be to put together a distributed system from individual subsystems (digitizers, preprocessors, array processors, disks, high-resolution displays, etc.) and to link them all together with a high-capacity LAN, capable of the transfer of complete images at near-real-time rates. This would result in a flexible system, reconfigurable and upgradable by simply adding more powerful devices to the existing installation, and also ensure a standard, unified interface between different components. Some possible architectures for the network are discussed. Other factors affecting the design are also considered, based on typical medical imaging systems and needs. A parallel is drawn between the proposed system and the Digital Imaging Network for the Picture Archiving and Communications System (DIN/PACS) currently under development.
