The definitive guide to pacs — now with more clinically applicable material In recent years, the field of picture archiving and communications systems—pacs—and image informatics has advanced due to both conceptual and technological advancements. This edition of pacs and imaging Informatics: Basic Principles and Applications addresses the latest in this exciting field. In contrast to the previous edition, this updated text uses the framework of image informatics, not physics or engineering principles, to explain pacs. It is the only resource that thoroughly covers the critical issues of hardware/software design and implementation in a systematic and easily comprehensible manner. To strengthen and update the book, the author: Emphasizes clinical applications of pacs and integrates clinical examples throughout the text Reflects the many changes in the field, with new chapters on Web-based pacs, security, integrating the healthcare enterprise, clinical management systems, and the electronic patient record Uses the framework of imaging informatics to explain pacs, making the book accessible to those without advanced knowledge of physics, engineering, math, or information technology Explains how pacs can improve workflow, therapy, and treatment With the most systematic and thorough coverage of practical applications available, this text is the complete guide for all those involved in designing, implementing, and using pacs. Professionals in medical and allied health imaging informatics; radiologists and their technical staff; surgeons and oncologists and their teams; medical and electronic engineers; medical informaticians; and fellows, graduate students, and advanced undergraduates will all benefit from this valuable resource. "An excellent book for people involved in the design, implementation, or simply the operations of pacs and an appropriate textbook."— From a review of the previous edition in IEEE engineering in Medicine and Biology "The strength of the book lies i

Interoperability between viewers between different platforms, and different vendors is enabled. Three parts of this interoperability are distinguished: session control, audiovisual (multimedia) data exchange, and medical image sharing. The third component is discussed, assuming the use of existing standards for the first two parts.

The Web browser is an environment for the rapid development of an effective and inexpensive picture archiving and communication system (pacs) viewer. A browser-based viewer is developed, from the inception and prototype stages to its current state of maturity. The many potential advantages to a browser-based viewer, even when native viewers already exist in the system, are discussed.

Describes challenges in using image processing and automated feature extraction for improving diagnostic accuracy. The generalization of digital technology in medicalimaging makes it possible to design computer-aided decision-support tools to help resolve the difficulties encountered by radiologists. It has already been demonstrated that image processing and automated feature extraction can help improve diagnostic accuracy in some applications. Future challenges are for the development of vision techniques tailored for a wider range of imaging modalities and pathologies the design of methods for the combination of several classifiers, and the implementation of expert systems incorporating both low-level feature extractors and high-level clinical knowledge. After evaluation, these tools will be integrated in pacs systems to highlight regions of interest and to provide clinicians with a documented second opinion. Then, such integrated systems can be used routinely in the clinical practice and teaching of radiology.

As pacs implementations increase during the new millennium, the need to plan and execute the movement of a live pacs from an existing facility into a replacement hospital increases. Such an tradertaking should support not only the physical movement of the existing pacs but also the continuous support of clinical radiology operations throughout the transition period. This paper will describe two successful transitions of live pacs into newly constructed replacement hospitals. In 1994 the Brooke Army medical Center transitioned into a newly constructed 450-bed facility in San Antonio Texas. In 1999 a similar movement of the Elmendorf Air Force medical Center was successfully accomplished in Anchorage Alaska. Both moves provided continuous operations of the Radiology Department and full clinical services in the old facilities in a near filmless mode while fully supporting the simultaneous installation and testing of new pacs components and pacs-to-modality interfaces in the new facilities. The process also included the migration of the image archives and acceptance testing of the final installation. While the exact migration process must differ, depending on the pacs architecture and the facility transition plans, these two examples provide a general framework for the issues and strategies for such a move.

The flexibility and interoperability between viewers and archives should be optimized for price/performance. An Application Program Interface (API) that gives additional flexibility and more possibilities for interoperability is defined. It is based on accumulative experience in the Java community. This proposal is called JDAPI for Java DICOM API, since the Digital imaging and Communications in Medicine (DICOM) data model is reflected within. The most important advantage of the proposal in defining a set of Java interfaces, is to allow an independent development of the viewer and of the archive.

Picture Archiving and Communication Systems (pacs) is a concept followed since the early 1980's by the radiological community as a future method of practising radiology. Some of the seminal papers for pacs were published in 1982. Although publications by Duerinckx, Maguiere, Horii, and Dwyer are generally considered to be the first pacs descriptions in literature, there have been descriptions of similar concepts before the 1980's, e.g. relating to workstations for medical image processing and to IMAC (Image Management and Communication). Soon after the first SPIE international symposium on pacs in the USA, first attempts of a filmless radiological department were made in Europe. The countries particularly active were The Netherlands, Belgium, France, Italy, Austria, Germany, and the U.K.

This paper describes the initial phases and configuration of the Picture Archive and Communication System (pacs) deployed at Northwestern Memorial Hospital. The primary goals of the project were to improve service to patients, improve service to referring physicians, and improve the process of radiology. Secondary goals were to enhance the academic mission, and modernize institutional information systems. The system consists of a large number of heterogeneous imaging modalities sending imaging studies via DICOM to a GE medical Systems PathSpeed pacs. The radiology department workflow is briefly described. The system is currently storing approximately 140,000 studies and over 5 million images, growing by approximately 600 studies and 25,000 images per day. Data reflecting use of the short term and long term storage is provided.
