Meta-Manager: A requirements analysis

Abstract

The digital imaging network-picture archiving and comrnunications system (DIN-PACS) will be implemented in ten sites within the Great Plains Regional Medical Command (GPRMC). This network of PACS and teleradiology technology over a shared T1 network has opened the door for round the clock radiology coverage of all sites. However, the concept of a virtual radiology environment poses new issues for military medicine. A new workflow management system must be developed. This workflow management system will allow us to efficiently resolve these issues including quality of care, availability, severe capitation, and quality of the workforce. The design process of this management system must employ existing technology, operate over various telecommunication networks and protocols, be independent of platform operating systems, be flexible and scaleable, and involve the end user at the outset in the design process for which it is developed. Using the unified modeling language (UML), the specifications for this new business rnanagement system were created in concert between the University of Arizona and the GPRMC. These specifications detail a management system operating through a common object request brokered architecture (CORBAJ environment. In this presentation, we characterize the Meta-Manager management system including aspects of intelligence, interfacility routing, fail-safe operations, and expected improvements in patient care and efficiency.

Saunders CompanyB EFORE 1997, the medical diagnostic imaging system (MDIS) predominated as the picture archiving communications system (PACS) in the majority of deployed sites within the Department of Defense (DOD) and the Veterans Affairs (VA). The benefits of this new technology have been described. These consist of reduced film-loss rates, reduced repeat rates, and near 100% availability of images. Report turnaround times were also favorably influenced.

The Application of Use Case Modeling in Designing Medical Imaging Information Systems

“…Next, deficiency is the pure evaluative methods of analytical models which do not seem to be considered as an independent subject and is presently one of the serious problems in health section software development [ 21 , 22 ]. In case enough attention is paid to this issue in the models architecture planning, the results will be valuable for improving information systems modeling process.…”
