Distributed file-management system for remote consultation and diagnosis in global PACS

Continuous advancement in the field of high speed computer networks and real-time distributed database technology have made new applications in the field of medical imaging possible. The Global PACS prototype is one such application which has been implemented on a national scale via wide area networks. It integrates different system components, such as imaging equipment, viewing workstations, database management and the archive system, fiber optic networks and a high-speed backbone network. Global PACS includes a distributed database archive system spread throughout wide geographical areas and interconnected via the Internet and NSFNET. This paper presents a new approach using a file management system for a Global PACS distributed database management and archive system.
