Paper Abstract

For PACS to be clinically desirable, transmiued imagery must be optimized for the various clinical and research tasks. There are several processes that potentially degrade the diagnostic utility of the iransmitted imagery. We examined our CommView PACS system at San Francisco VA Medical Center (SFVAMC) to determine if imagery was altered from the original during passage into and through PACS, and whether the alteration had any discernable effect on current or projected clinical utility of the imagery. Related operational considerations were also examined. This limited review of our CommView system indicates that the attenuation of the image data by frame-grabbing and inability of the workstation to work with processed rather than formatted data from computed radiography limits the potential capabilities of the workstation. The reversible compression algorithm for imagery archival functioned well, but serious high frequency aliasing was introduced in imagery reduced for transmission to remote viewing stations.
