“…A quasi validation of the user model is done by comparing the model behavior with the other models proposed in the literature and similarly dimensioned [1] [3], as well as via discussions made with the radiology department staff of a local hospital. …”

A simulation method for performance estimation and dimensioning a medical picture archival and communications system (PACS) is introduced. The introduced method makes use of a source layer model to simulate the behavior of a typical PACS user and server. As a case study for the application of the proposed methodology, the problem of dimensioning the PACS of a radiology department with a multitude of users and modalities is considered. Furthermore, the effect of additional database servers on the system performance is considered. Results are presented for two cases: i) for the system with radiologists, modalities, and database server(s); ii.) with modality traffic postponed to off hours, i.e., for the system with database server(s) and radiologists onl y.

Procedure of IMAC/PACS is ; survey of present situation, system analysis, optimized system design, installation, operation, and technology assessment.System design is discussed implying technology assessment. The author wants to emphasize that medical technology assessment begins with system design.Concrete method and procedure of technology assessment in IMAC/PACS are stated citing literature in this field.Especially the author proposes to establish standard for quantitative expression of efficacy, effectiveness, cost benefit and etc. in technology assessment, which must be applied both before and after IMAC/PACS operation. 154 0-8186-2195-8/91 $1.00 Q 1991 IEEE surveyed present situation of the University Hos,pital.
