Information relevant to radiological applications is commonly managed by several autonomous medical information systems including hospital information systems (HIS), radiological information systems (RIS), and picture archiving and communications systems (PACS). In this report, we expiain the need to coordinate these systems and to provide some framework in which they can exchange information. In the first half of this report, we describe the integration of a PACS system into a hospital operation. Next, we present the interfacing methods between the HIS and the RIS, and between the RIS and the PACS. Two methods are further detailed for the communication between the RIS and the PACS (1) the triggered database to database transfer, and (21 the query protocol. The implementation of the first method successfully allows RIS reports, procedure and patient demographic information to be displayed at the request of the user along with the associated images at a PACS workstation. The query protocol allows a PACS to dynamically query RIS information. It will be eventually integrated into the design of a scientific multimedia distributed medical database system built on top of the HIS, the RIS, and the PACS.

In this report we present an integrated picture archiving and communication system (PACS)-radiology information system (RIS) which runs as part of the daily routine in the Department of Radiology at the University of Graz. Although the PACS and the RiS have been developed independently, the two systems are interfaced to ensure a unified and consistent Iong-term archive. The configuration connects four computer tomography scanners (one of them situated at a distance of 1 km), a magnetic resonance imaging scanner, a digital subtraction angiography unit, an evaluation console, a diagnostic console, an image display console, an archive with two optical disk drives, and several RIS terminals. The configuration allows the routine archiving of all examinations on optical disks independent of reporting. The management of the optical disks is performed by the RIS. Images can be selected for retrieval vŸ the RIS by using patient identification or medical criteria. A special software process (PACS-MONITOR) enables the user to survey and manage image communication, archiving, and retrieval as well as to get information about the status of the system at any time and handle the different procedures in the PACS. The system is active 24 hours a day. To make the PACS operation as independent as possible from the permanent presence of a system manager (electronic data processing expert), a rule-based expert system (OPERAS; OPERating ASsistant) is in use to Iocalize and eliminate malfunctions that occur during routine work. The PACS-RIS reduces labor and speeds access to images within radiology and clinical departments.
Electronic archiving for radiology image management systems
[1993] Proceedings Twelfth IEEE Symposium on Mass Storage systems, 2000
Electronic archiving for radiology image management systems requires terabytes of mass storage and large retrieval rates. The use of electronic archiving in a radiology department must be supported by image acquisition nodes, high data rate local area networks, ultrahigh resolution gray-scale display workstations, and hardcopy image recording stations. The requirements for mass storage of radiographic images and the required support system is presented.
Research and teaching access to a large clinical picture archiving and communication system
Journal of Digital Imaging, 2001
Purpose: To identify practical issues surrounding delivering digital images from picture archiving and communication systems (PACS) for research and teaching purposes. The complexity of Digital Imaging and Communications in Medicine (DICOM) access methods, security, patient confidentiality, PACS database integrity, portability, and scalability are discussed. A software prototype designed to resolve these issues is described.System Architecture: A six-component, three-tier, client server software application program supporting DICOM query/retrieve services was developed in the JAWA language. This software was interfaced to a large GE (Mt Prospect, IL) Medical Systems clinical PACS at Northwestern Memorial Hospital (NMH).Conclusion: Images can be delivered from a clinical PACS for research and teaching purposes. Concerns for security, patient confidentiality, integrity of the PACS database, and management of the transactions can be addressed. The described software is one such solution for achieving this goal.
Completion of a hospital-wide comprehensive image management and communication system
Society of Photo- …, 1989
A comprehensive image management and communication (IMAC) network has been installed at Georgetown University Hospital for an extensive clinical evaluation. The network is based on the AT &T CommView system and it includes interfaces to 12 imaging devices, 15 workstations (inside and outside of the radiology department), a teleradiology link to an imaging center, an optical jukebox and a number of advanced image display and processing systems such as Sun workstations, PIXAR, and PIXEL. Details of network configuration and its role in the evaluation project are discussed. 1.0 INTROpUCTIOlY The management of the vast amounts of medical images and information generated by today's clinical services is a growing problem. The solution to the problem will increasingly require the use of advanced computer-based technologies U1I in data storage, image display and communication, and human engineering. The progress of individual technologies has been rapid; however, system integration and user acceptance have been slow in coming. Though the new imaging technologies have given the radiologist a powerful set of new diagnostic tools, the quality of radiology service has not experienced similar revolutionary improvements over the decade. In fact the use of many imaging modalities has imposed additional difficulties in managing films and data. New imaging systems have created a number of difficulties in managing radiology images and information because (a) they are often produced in physically distant locations, (b) images are presented in varying film formats, (c) radiology service is highly subspecialized and there is a greater need to review multimodality images, and (d) within large and complex medical care facilities there is an increasing number of competing demands for radiological images. It is generally accepted that the management of radiology images can be improved by using some computer based image system. However, opinions vary. What type of approach would be desirable? The possible solutions [2] will depend on such factors as the nature of radiology service, the types of images, and clinical workload. The use of computer based image management is becoming a major challenge and it is expected to generate a great deal of interest in the near future. How could this electronic technology enhance the quality and efficiency of radiology service? How should such technical capabilities be utilized to address the critical issues in a cost efficient way? Would the users, radiologists, and referring physicians embrace the use of this new technology? What kind of impact would IMAC technology have in the way that radiology service is performed. How should this technology be deployed to meet the combat casualty care needs of the Army? The project [3] at Georgetown University is designed to address these questions with close collaboration with a number of universities, government agencies, and military experts. While many specific technical issues involving display resolutions, image processing methods, and data compression techniques are an important part of the project, additional emphasis is placed on the system-wide issues of IMACS as an integral part of patient care.
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...
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.
