基于CORBA的医院信息系统与PACS的分布式集成研究

在实际医学应用中 ,医生需要及时获得病人的有关图像和文本记录信息。这些信息有助于医生进行病历诊断 ,临床试验和研究分析。但是这些信息分布零乱 ,并且位于不同的系统上 ,如图像管理和通信系统 (Picturearchiving and comm unication information systems,PACS) ,医院信息系统 (Hospital inform ation systems,HIS)等 ,这些系统使用不同的标准和协议 ,并且都不支持分布式操作 ,使系统间信息不能完全共享。为了实现各种医学系统间的分布式操作和信息的共享 ,本文结合当前流行的 WWW技术 ,利用分布式处理软件 (Common object requestbroker architecture,CORBA) ,提出了一种基于 WEB的 PACS和 HIS分布式集成方法 ,该方法将图像和文本信息系统及各种医学应用都看作是 CORBA组件对象 ,把对这些系统和应用的操作都当作是对应用对象的处理 ,利用面向对象的技术实现了对 PACS和 HIS系统的分布式集成和互操作 ,并且利用 WEB技术实现了信息的共享

Study on the Distributed Integration of the HIS and PACS Based on CORBA

In medical clinical practice, physicians need to acquire the image and text information of the patient. All the information will be of benefit for physicians to diagnose disease, improve clinical treatment, and do research work. But the information is distributed in different systems ,such as medical image information in PACS(Picture Archiving and Communication System) and text records in HIS(Hospital Information System). Today many hospitals are suffering from lack of an integrated system with PACS and HIS. This paper compares PACS with HIS and puts forward a distributed integration method of integrating the PACS and HIS with the prevailing WWW technology. In such a method,the image and the text information are regarded as the common object and the operation whereon as the object operation. Thus the method integrates the PACS with HIS effectively and implements the information resources sharing with the use of web technology.
