当今很少有信息系统提供灵活的方法来定义和管理放射学流程的自动化部分，为整个医疗保健组织提供临床成像服务。它们中更少有提供一致的架构，可以轻松科普应用程序的异构性和不可避免的本地适应，并可以集成临床和管理信息，以帮助更好的临床，运营和业务决策。我们描述了一个创新的企业架构的图像信息管理系统，以满足需求。这样一个系统是基于生产工作流管理，分布式对象计算，Java和Web技术的相互作用，并在放射学操作的深入领域的知识。我们的设计采用了“4+1”建筑观的方法。在这种新的架构中，PACS和RIS成为一体，而用户交互可以通过自定义的工作流程自动化。临床服务应用程序作为活动组件实施。它们可以合理地被本地适配的应用程序所取代，并且可以成倍增加以实现容错和负载平衡。此外，工作流程化的数字放射学系统将提供强大的查询和统计功能，用于管理资源和提高生产力。本文的研究为图像信息管理提供了一个新的方向。我们说明了创新的设计与实施系统的例子。
Few information systems today offer a flexible means to define and manage the automated part of radiology processes, which provide clinical imaging services for the entire healthcare organization. Even fewer of them provide a coherent architecture that can easily cope with heterogeneity and inevitable local adaptation of applications and can integrate clinical and administrative information to aid better clinical, operational, and business decisions. We describe an innovative enterprise architecture of image information management systems to fill the needs. Such a system is based on the interplay of production workflow management, distributed object computing, Java and Web techniques, and in-depth domain knowledge in radiology operations. Our design adapts the approach of "4+1" architectural view. In this new architecture, PACS and RIS become one while the user interaction can be automated by customized workflow process. Clinical service applications are implemented as active components. They can be reasonably substituted by applications of local adaptations and can be multiplied for fault tolerance and load balancing. Furthermore, the workflow-enabled digital radiology system would provide powerful query and statistical functions for managing resources and improving productivity. This paper will potentially lead to a new direction of image information management. We illustrate the innovative design with examples taken from an implemented system.
