Validation-driven modeling of a PACS database in a shared-file system environment

摘要

Abstract: Siemens Gammasonics and Loral Western Development Labs have conducted a series of discrete event simulation models to investigate and evaluate different design concepts of large picture archive and communication systems (PACS). The system model, the communication network model, and the workstation model were all initiated to be able to identify the most efficient system capable of supporting large, fully digital hospitals. Siemens and Loral have delivered the first systems. Continuing modeling activity explores opportunities to enhance the performance of the system by investigating new technologies, ideas and changes throughout the life cycle of the Siemens/Loral PACS. This paper describes the database modeling approach based on the validation of currently installed systems, the performance results, how to improve and tune the system under future data growth conditions with minimum costs, and how it fits in the overall Siemens/Loral Modeling Schema. !6
