Picture Archiving and Communication System (PACS) networking: Three implementation strategies

Computerized Medical Imaging and Graphics, 1991

This paper outlines the diverse Picture Archiving and Communication Systems (PACS) networking implementation strategies at the University of California at Los Angeles, the University of Florida, and the University of Kansas. At the University of California at Los Angeles, a very high-speed network has been integrated into a hierarchical networking strategy, resulting in an entirely customized network for the local transmission of images. The University of Florida has chosen to implement networks for local transmission of images using commercially available equipment. The University of Kansas, specializing in teleradiology applications, uses commercial telecommunication circuits to implement long distance referral services to small hospitals.

Infrastructure design of a picture archiving and communication system

American Journal of Roentgenology, 1992

A picture archiving and communication system (PACS) infratructure is the necessary framework to integrate distributed and #{149}eterogeneous imaging systems, provide intelligent database nanagement of all radiology-related information, arrange an eficient means of viewing, analyzing, and documenting study re-3u1t5, and furnish a mechanism for effectively communicating study results to the referring physician. The PACS infrastructure consists of a basic skeleton of hardware components integrated by standardized, flexible software subsystems. This review de

Design and implementation of a picture archiving and communication system: The second time

Journal of Digital Imaging, 1996

This report describes the authors' experience in the design and implementation of two large scale picture archiving and communication systems (PACS) during the past 10 years. The first system, which is in daily clinical operation was developed at University of California, Los Angeles from 1983 to 1992. The second system, which continues evolving, has been in development at University of California, San Francisco (UCSF) since 1992. The report highiights the differences between the two systems and points out the gradual change in the PACS design concept during the past 10 years from a closed architecture to an open hospitalintegrated system. Both systems focus on system reliability and data integrity, with 24-hour on-line service and no Ioss of images. The major difference between the two systems is that the UCSF PACS infrastructure design is a completely open architecture and the system implementation uses more advanced technologies in computer software, digital communication, system interface, and stable industry standards. Such a PACS can withstand future technology changes without rendering the system obsolete, an essential criterion in any PACS design.

Implementation of a large-scale picture archiving and communication system

Computerized Medical Imaging and Graphics, 1993

This paper describes the implementation of a large-scale picture archiving and communication system (PACS) in a clinical environment. The system consists of a PACS infrastructure, composed of a PACS controller, a database management system, communication networks, and optical disk archive. It connects to three MR units, four CT scanners, three computed radiography systems, and two laser film digitizers. Seven display stations are on line 24 h/day, 7 days/wk in genitourinary radiology (2K), pediatric radiology in-patient (1K and 2K) and outpatient (2K), neuroradiology (2K), pediatric ICU (lK), coronary care unit (lK), and one laser film printing station. The PACS is integrated with the hospital information system and the radiology information system. The system has been in operation since February 1992. We have integrated this PACS as a clinical component in daily radiology practice. It archives an average of 2.0-gigabyte image data per workday. A 3-mo system performance of various components are tabulated. The deployment of this large-scale PACS signifies a milestone in our PACS research and development effort. Radiologists, fellows, residents, and clinicians use it for case review, conferences, and occasionally for primary diagnosis. With this huge-scale PACS in place, it will allow us to investigate the two critical issues raised when PACS research first started 10 yrs ago: system performance and cost effectiveness between a digital-based and a film-based system.

Concurrent processing for picture archiving and communication system (PACS)

Proceedings of IEEE Singapore International Conference on Networks and International Conference on Information Engineering '95, 1995

To improve medical services and' reduce costs, we develop a framework of an advanced picture archival and communication system (PACS) where computational intensive algorithms are processed on a network of workstations. Although real-time processing of certain computational intensive tasks is generally not achievable in cluster environment, we demonstrate that reasonable speed improvement can be obtained to improve the system response time. This paper describes the concepts of advanced PACS in which multimedia annotations, computer aided image analysis, 30 visualisation and coding are integrated into PACS as a single entity. The proposed sysfem is implemented using a ClienUServer model on gen era1 purpose computing workstations. The experimental results and performance of our proposed system indicate that PACS could take advantage of recent advances in concurrent processing to include advance features, which would otherwise be found in high-end computer system only.

Practical issues in picture archiving and communication system and networking

Indian Journal of Radiology and Imaging, 2010

Picture Archiving and Communication System (PACS) is a key workflow tool in the functioning of radiology departments worldwide, today, and its utilization is rapidly growing in India. The key challenges in PACS implementation are related to vendor and feature selection, integration with the existing HIS, user training, maintenance and scalability to meet increasing demands. Additionally, the networking requirements that PACS imposes on hospital networks are not insignificant. This article attempts to review these issues from the standpoint of what a prospective or new user needs to know.

Picture Archiving and Communication System Design and Implementation

2016

PACS (Picture archiving and communication system) has been vastly introduced as a reliable alternative to the conventional film- and paper-based healthcare system. It has been in existence for several years and has become an integral part of the infrastructure of radiology and imaging departments across the world. Services provided by PACS establish a platform for the diagnosis of different diseases. PACS serves as a more convenient means of teaching students of radiology, it also reduces transmissions time requirement for referral cases and access time to images and radiological report over the network and improves on the time of patient consultation. In this paper we discuss the construction of (PACS) for hospitals that provides electronic storage, retrieval, manipulation, distribution and presentation of medical images using a popular format named DICOM. This research work implements a PACS model with the incorporation of new features. Its objectives were achieved: converting non...

PACS database architecture and design

Computerized Medical Imaging and Graphics, 1991

PACS (Picture Archiving and Communication Systems) database design requires careful understanding of the data and processing needs of radiologists, referring physicians, radiology staff, administrators, and researchers. Due to access requirements, the physical implementation for the management of small text data sets differs from the implementation strategy for large image data sets (centralized vs. distributed storage strategies). In this paper we discuss the database structure, storage architecture, file placement strategies, and administration considerations of the UCLA PACS.
