Abstract
Telemedicine systems have been rapidly increasing in number and size over the past decades. This increasing trend intensifies the need for tele-medicine in the area of national healthcare system. The increasing size of distributed telemedicine systems creates problems of data integration, vendor lock-in, and interoperability. In this paper, we present a next generation telemedicine system architecture, which is based on service oriented architecture (SOA). We believe SOA can resolve several problems in today's telemedicine systems. In the current infrastructure of telemedicine, several problems have been identified such as users becoming limited to a single vendor. Therefore, we performed requirements analysis and evaluation to propose a robust solution to avoid the problem of vendor locking and interoperability.
