European picture archiving and communication systems projects.

Picture archiving and communication systems (PACS) are among the most promising information technologies in health care. They are, however, still in the development phase, and their implementation is taking longer than was predicted in the 1980s. Evaluation of these PACS implementations is also much more difficult than was expected. Local, very specific settings and lack of standard methodology make a comparison of tangible and intangible factors very cumbersome. This difficulty has resulted in very divergent opinions in the literature regarding the objectives, realizations, and achievements of PACS. Different approaches for image acquisition, processing, communication, and display have been supported in a wide variety of conferences and in a few key publications. Different approaches are particularly noticeable in Europe and are exemplified by a spectrum of single and multivendor PACS realizations. Some of the most significant of these developments are reviewed.

[Computer-assisted radiology].

New digital imaging modalities and more sophisticated image processing systems will have a profound effect on those areas of medicine concerned with imaging. This mainly means computer-assisted radiology (CAR) and implies a transition from analog film systems to digital imaging systems, integration of digital imaging modalities through picture archiving and communication systems (PACS) and the graduated employment of image-oriented medical work stations (MWS) for computer-assisted representation, communication, diagnosis, and therapy planning.

[The PACS model plan at the Freiburg University Clinic. A first step toward a radiologic picture archiving and communication system].

In a study performed at several clinical departments of the University of Freiburg, West Germany, it was found that approximately 180,000 patient examinations based on computed tomography, magnetic resonance, nuclear medicine, ultrasound as well as digital and conventional radiography, produce over 1,000,000 pictures. It was assumed that modern technologies can greatly facilitate the handling of such a quantity of images. This applies to diagnosis and therapy planning as well as to communication and archiving of this large amount of data. The study also assumes that the technologies to be considered, e.g. fiber optical networks, optical archives and medical work stations, which represent the main components of PACS, should be introduced in a stepwise manner following a clear overall conception. As the first step the implementation of a local area network (LAN) in the departments of radiology and general surgery is planned. Important criteria for the selection of these particular departments are improvements in health care for a maximum number of patients and in the working profiles for the greatest possible number of physicians and assistant personnel. A cost reduction as compared to the present system through more efficient communication and archiving of the digital images is expected. New perspectives for medical research as well as for medico-technical developments are also expected. Examples are the 3-D representations of human anatomy and the manufacturing of custom-designed prothetic devices. Scheduling and budgetary plans for equipment and manpower are further study results for the Freiburg PACS-Project.
