PACS workflow analysis and optimization using a modeling and simulation methodology

摘要

Abstract: A majority of distributed applications in Radiology are being developed and deployed without serious regard to their impact on currently deployed networks or how various network configurations impact end-user response-time. Typically the blame for these delays are directed unthinkingly at the existing network bandwidth. A more thoughtful planning process would consists of analyzing the latency in the various components of the transmission process: the network, computer hardware and computer software processes. We have developed a methodology for the analysis of imaging network workflow, which has been applied to the ultrasound component of the PACS at the University of Washington. !8
