A Second Generation PACS Concept

The term picture archiving and communications system (PACS) was initiated during the first International conference and workshop on the topic sponsored by The International Society for Optical Engineering (SPIE) in Newport Beach, California in 1982. The research and development (R&D) progress for PACS has been slow until 1988. The earlier PACS modules were mostly off the shelf components connected together to solve a very specific clinical problem. The three major players in PACS R&D are the European countries, United States of America, and Japan. For various reasons, the European coun tries concentrated in modeling and simulation, U.S.A. pre ferred in-house development or purchased PACS modules from a manufacturer, whereas Japan organized the PACS as a national project. Between 1989 and 1990 PACS R&D took a dramatic positive turn. Large scale P ACS projects were planned and some are of implementation, especially in newly con at various stages structed hospitals. Examples are the Hokkaido University, Japan; Hammersmith Hospital, United Kingdom; Social and Medical Center East (SMZO), Vienna, Austria; the U.S. Armed Force Medical Diagnostic Imaging Support (MDIS) project; and the UCLA Medical Plaza ambulatory care center. Another phenomenon is the organization of the EC-countries which provides a tremendous impetus for the European PACS R&D efforts. This book "Hospital Integrated Picture Archiving and Communication Systems: edited by Professor M. Osteaux and others is a direct product from these efforts.

Klappentext

This book presents the results of a multidisciplinary,cooperative project which was jointly undertaken by researchteams from universities, industry, and university hospitalsin five European Community countries. The study shows howthe digital management of diagnostic imaging pictures can bemade effective in the clinical environment. The book dealsin detail with the distinct issues of PACS (PictureArchiving and Communicatioins Systems) integration, such asmedical requirements, communication with othersystems,networking, workstations, database, indexing methods, andstandards. A clear collective view is sythesized on thearchitectureof a second-generation PACS, taking intoaccount the diverse features of thepresent state of the artand expected future enhancements of PACS technology.
