Samsung Medical Center (SMC) is a brand new hospital of about 1,000 patient beds which has implemented a successful picture archiving and communications system (PACS) since November 1994. The goal of SMC PACS was to implement a large-scale filmless PACS in four phases. SMC chose the turn-key based implementation method regarding the time frame. The departments of orthopedic surgery, neurosurgery, neurology, emergency room and surgical intensive care unit were selected for the first phase of PACS implementation. SMC reduced the confusion and the discomfort of medical doctors during the transition period of film and PACS operation. This paper describes the process of the clinical implementation of SMC PACS; goal and scope, implementation strategy, system installation and training, and clinical operation and maintenance.

This paper presents the design and implementation of a distributed (image) database on a TCP/IP network of heterogeneous machines. It is based on the tagged container idea: a dataset is treated as a black box and ragged with a description, which is stored in a freely searchable database. Using readily available public domain utilities with a minimum of "glue logic", this is a vendor-neutral, low-cost system. Furthermore, it supports the idea of collaboration by allowing multiple servers running under the policy of different departments.

Many hospitals and medical centers have computerized information systems either within radiology (RIS) or throughout the hospital (HIS). These different systems, which include, order entry, scheduling, transcription, ADT, and other functions are often operational in institutions that are considering installing an image management and communications system (IMACS). Since these systems have information that is crucial to an effective operational IMAC system it is necessary to communicate information between an information system and an IMACS. The mechanisms for sharing information between hospital and radiology information systems and IMAC systems is quite varied. Data entry can be duplicated into the different systems, data can pass from one system to the other, data can pass between the systems, or it can reside in a common database. This paper discusses information and image management systems, different mechanisms for communicating information between these systems, as well as the advantages and disadvantages of the communication mechanisms.

DICOM database functions are employed to locate stored images and to update and retrieve attributes of specific object instances. The Query/Retrieve service class provides a set of consensus schema (the Q/R models) that support a particular view of patient data. This view adequately supports primary reading, i.e., it focuses on organizing images into studies and linking studies to patients, but it does not necessarily support the types of access required for retrieval from a digital file room. As the DICOM standard evolves it is necessary to carefully choose services and models that make sense for the medical imaging and image management marketplace. Should DICOM continue to define it's own proprietary access methods or adopt standard methods? Existing and near-term future standards for database access include: RDA, SQL3 and SQL/CLI. These standards will be evaluated as possible future bases for advanced DICOM database access services.

The Department of Radiology at Brooke Army Medical Center conducted a prospective comparison analysis of the utility of soft copy versus hard copy interpretation. We digitally acquired 218 examinations, storing the information on an optical drive. The acquired images were printed on film for initial hard copy interpretation. In those instances where we felt that additional clarification was warranted we accessed the entire data set on the Picture Archiving and Communication System (PACS). The comparison analysis involved a total of 218 radiographic examinations. On 93 studies, (43% of the total) we determined that final radiological disposition required further radiological. Further evaluation by accessing and manually manipulating the data on the computer monitor occurred. Upon reviewing the data we found that in 37% of the 93 cases, soft copy access allowed us to come to a conclusion without additional imaging.

The WEBRAD (Web Radiology) project is a testbed to demonstrate the use of standard Internet tools and techniques applied to teleradiology. This is a joint project between the Radiology Department of the Imaging Science and Information Systems (ISIS) Center at Georgetown University Medical Center (GUMC) in Washington DC and the Analogic Corporation, Peabody, Massachusetts. This project utilizes standard TCP/IP client-server tools for the World Wide Web (WWW), Web-based hypertext pages for navigation, Web-based image viewing tools and Web-based form interaction to conduct routine clinical teleradiology diagnosis. The objective of this project is to develop a user-friendly radiologist-oriented interface using the familiar navigation and viewing tools of the WWW.

The purpose of the Global Standard Operating Procedures for Telepathology (GSOP-TP) is to establish a systematic procedure for the receipt, accessing and processing of mutual case exchange/consultation between international centers via telepathology. These guidelines have emanated from the collective experience of our centers and are intended as recommendations for information exchange in telepathology.

This paper describes a Teleradiology experiment which is being held in Portugal involving Hospitals in the northern region of the country. These healthcare units are connected by means of ISDN basic accesses (2B+D) and use the INTERACT system. The system is based on Personal Computers running Windows, and creates an integrated environment for cooperative work in Medical Imaging. A DICOM interface module is also provided as well as basic tools (telepointer, magnifying glass, contrast manipulation). The system has been running in two hospitals of Porto area with good user acceptance. Organizational changes must be implemented in the involved units for a perfect integration of these new telematic tools.

A picture archiving and communication system (PACS) can provide support to non-clinical departments in a large medical center such as medical media or photographic services. The two PACS at the Baltimore VA Medical Center are utilized by the medical media department to facilitate acquisition and archival of a wide spectrum of hospital images. The decreased dependence upon the medical media department for slides due to the projection television workstations in the auditorium and the ability to capture images directly from the PACS has resulted in significant increases in efficiency, productivity and quality in the medical media department.

The management of images on a full hospital picture archiving and communication system (PACS) is a complex requirement. In order to work efficiently, a "worklist" mechanism is provided to present the radiologist with a simple "view" of his/her work. Worklists are radiologist-specific and consist of unread examinations which are automatically apportioned between radiologists based on local departmental procedures (e.g. body part, modality, etc.). Furthermore, simple "shortcuts", such as a NEXT function and a quick way to know about and to open STAT examinations are mandatory for efficient clinical operation. The presentation of images for new and historical exams on a softcopy workstation should appear similar to the familiar film alternator for speed of operation and ease of use by physicians who are trained on hardcopy film. When the imaging system extends across several medical facilities, the management of images becomes more complex. A radiologist's work may extend across several facilities. Radiologists at several facilities may collectively read exams at all of the facilities. The radiologist worklist must present a view of the new exams anywhere in the system. The worklist must be able to support several radiologists over the system working of the unread examinations simultaneously. This paper describes the concepts for image selection and presentation at PACS workstations both within a medical treatment facility and distributed across several hospitals and clinics.
