摘要
大量信息孤岛的存在使得区域化成为当前PACS系统发展的一个主要趋势。传统PACS结构多是基于C/S体系,无法满足区域信息系统维护管理的需求。针对该结构局限性,本文提出了基于CORBA技术的分布式区域性PACS结构,并对PACS对象进行了设计与封装。通过将一系列逻辑独立、功能相关的PACS服务对象挂载于ORB软总线上,可方便地组建不同规模的PACS系统。该方法突破了传统结构的瓶颈,具有良好的兼容性和可扩展性。
Regionalization has become one of the most important trends in the development of picture archiving and communication systems （PACS） due to the existence of large amounts of information islands. The conventional PACS designed according to the DICOM standard on the basis of the C/S structure fails to meet the demand of regional information system maintenance. A regional PACS system based on common object request broker architecture （CORBA） distributed technology is therefore proposed and implemented. This article describes the design and packaging of the PACS objects. When mounting a series of separate logical and related functional PACS objects on the ORB bus, the multi-scale PACS systems can be established. This method eliminates the limitation of the C/S structure and offers good compatibility and scalability.
