title: Implementation of a radiology electronic imaging network: the community teaching hospital experience.
abstract: Because of their typically small in-house computer and network staff, non-university hospitals often hesitate to consider picture archiving and communication system (PACS) as a solution to the very demanding financial, clinical, and technological needs of today's Radiology Department. This article presents the experiences of the 3-year process for the design and implementation of the Radiology Electronic Imaging Network (REIN) in the Department of Radiology at The Western Pennsylvania Hospital (WPH). WPH embarked on this project in late 1994 to find a solution to the very pressing demands to reduce operating costs and improve service to primary care clinicians, both on-site and at WPH-affiliated clinics. A five-member committee consisting of in-house medical, administrative, information services, and medical physics staff was formed to design a network that would satisfy specific needs of WPH by using a phased mini-PACS approach and to select the various vendors to implement it. Suppliers for individual mini-PACS were selected to provide modality-specific solutions. For the backbone network, vendors were evaluated based on their technological progress, competence and resources, the commitment of the company to the imaging network business, and their willingness to embark on a mid-sized PACS project such as this. Based on patient volume, workflow patterns, and image quality requirements, the committee produced proposals detailing number and location of workstations, short- and long-term memory requirements, and so on. Computed tomography/magnetic resonance imaging, computer radiography, ultrasound, nuclear medicine, digital fluoroscopy, and angiography mini-PACS have been implemented over the past 2 years, and most of these are already integrated into the main REIN. This article presents detailed information concerning the design, selection and implementation processes, including storage requirement calculations. This indicates that PACS implementation is achievable for community hospitals with small computer, networking, and physics departments. Also presented are recommendations concerning design and vendor selection, that may be helpful for similar institutions.
