Abstract
The nation's hospitals have long used distributed data processing as a means of reducing operational costs and providing timely service. Radiology Departments are now also taking advantage of these facilities in order to decrease the cost of producing and archiving radiological images. A typical medium scale hospital consumes large quantities of silver oxide film which, along with attendant labor costs, is expensive compared with costs for digital image processing technology now available. Using this technology large image files can be stored and retrieved through local area networks that can also support the transaction traffic essential in a hospital environment. The evolving systems are called Picture Archiving and Control Systems (PACS). PACS will include radiology imaging equipment, distributed and central image archiving facilities, and significant numbers of user work-stations and graphics display nodes. The devices will be interconnected by high speed local area networks capable of distributing information ranging from simple control messages to large image files of several megabytes in a fashion offering most users a response time of several seconds. This paper will illustrate the PACS system concept, present a queuing model approach to analyzing PACS performance, and discuss results acquired for a variety of parametric samples. The IBM Research Queuing Package (RESQ) has been used for the exercise and will be discussed sufficiently for the reader to appreciate its capability. RESQ simulation results indicate that system response times will be more dependent on the internal architecture and programs of the workstation than on the speed of the transmission media.
