Paper Abstract

A complete PACS must store images for decades. For reasons of either media life or drive obsolescence, no storage technology can practically retain data for much more than ten years. Procedures for migration of data to new media must be part of the system to provide the necessary storage life. In preparation for procurement of a PACS archive, clinical procedure volume and use patterns in the Department of Radiology were analyzed and projections of storage, network and retrieval requirements were developed. The analysis showed that an archive based on magnetic disk for short term storage and duplicate copies of high density magnetic tape for long term storage should meet the complete archiving needs of the Department. Advance notice of the need for retrievals from long term storage must be provided by the Radiology Information System for efficient functioning of the archive. The organization and data migration policies of the archive being procured are described.
