Author Affiliations +
The University of Pennsylvania Medical Center has been operating a prototype clinical PACS for a number of years. The details of this implementation have been described elsewhere. Early on in the design phase we realized the need to pre-fetch images on a PACS network and incorporated rule-based pre-fetch mechanisms into our Folder Manager software suite. As our PACS expanded and as the pool of users increased to include MR technologies and researchers in addition to radiologists, the case for an on-demand retrieval mechanism became compelling. The design of such a paradigm posed special problems in that the system had to be robust and user-friendly. This paper discusses the design and implementation of such a system. Usage statistics collected over a one-year period are also presented. The retrieval profile shows certain patterns that can be exploited to improve the design of the PACS.
