Communication software for physicians' workstations su

摘要

Abstract: This paper describes a software communication architecture for medical imaging services. This work aims to provide to the physician the communication facilities to access and track a patient's record or to retrieve medical images from a remote database. The proposed architecture is comprised of a communication protocol and an application programming interface (API). The implemented protocol, namely the Telemedicine Network Services (TNS) protocol, has been designed in agreement with Open System Interconnection (OSI) upper layer protocols already standardized. Based on this concept an OSI-like interface has been developed capable of providing application services to the application developer, and thus facilitating the writing of medical application. TNS protocol has been implemented on top of TCP/IP communication protocols, by implementing OSI presentation and application services on top of the Transport Service Access Point (TSAP) which is provided by the socket abstraction on top of the TCP. !17
