Paper Abstract

The Radiology Department at the Hospital of the University of Pennsylvania is currently expanding its prototype Picture Archiving and Communications System ( PACS ) into a fully functional clinical system. The fi rst phase of this expansion involves three major efforts: the upgrade of the 10-Mbit token-ring to an 80-Mbit backbone with associated subnets, the implementation of a large-scale image archive, and, an interface between the PACS and the Department's Radiology Information System. Upon completion of this phase, the PACS will serve the storage and display needs of four MRI scanners and four of the Hospital' s Intensive Care Units . To achieve these objectives the Department entered into a joint development agreement with Vortech Data Inc. to develop applications-software for an optical jukebox-based image archive. This paper describes the developmental effort with special reference to the Image Archival and Retrieval System ( IRS). The IARS has three major features: a robust ACR/NEMA style protocol for external communication, a hierarchical storage system that incorporates magnetic, optical and shelf storage systems, and, a storage capacity that can be incrementally expanded from 25 GigaBytes to 7 TeraBytes.
