摘要
网格是集成和并行的计算与资源环境,核心是在异构和分布式的网络环境中实现资源共享。网格医疗信息系统的核心是医疗资源的共享和服务系统的建立。文中提出了基于服务网格的医疗信息系统体系结构,并对网格开发工具及其相关技术进行研究,给出了基于网格技术的医疗信息系统的应用实例。
＂Grid＂ is a type of parallel and distributed system that enables the sharing,selection,and aggregation of geographically distributed ＂autonomous＂ resources dynamically at runtime depending on their availability,capability,performance,cost,and users quality-of-service requirements.There are many obstructs on the sharing of resource in the Integrating distributed heterogeneous systems. For Medical information system based on Service Grid,it mainly discuss the sharing problem and create the service system.The paper describes the architecture of medical information system based on Service Grid.The grid development tool-Globus tookit 3.0 and some grid-related technologies are introduced. An application on medical information system based on grid is provided.
