基于HL7与DICOM的医疗信息集成交换服务中间件

Service Middleware of Medical Information Integration and Exchange Based on HL7 and DICOM

医疗信息集成交换是解决医疗信息互操作性与信息孤岛的有效方法,是医疗信息共享的基础。本文以医疗文本与医学影像信息为集成对象,以DICOM和HL7消息、数据集为集成交换单元,以高效的DICOM、HL7消息构建与解析方法为基础,设计并实现了一种通用的医疗信息集成交换服务中间件。实验表明,原型系统能够实现数据库、DICOM、HL7消息之间的集成与交换,为解决医疗信息孤岛提供了可行方案,为建立统一的医疗信息集成与共享平台打下了良好的基础,并在云南省社会发展科技计划项目"开放式医疗信息集成系统开发与示范"中得到了应用。

Medical information exchange and integration is the effective method to solve the interoperability and medi- cal information island, and is the basis of medical information sharing. In this paper, we take medical texts and medi- cal images as the basic integrated objects, DICOM, HL7 messages and datasets as the integrated units, efficient DI- COM, HL7 message construction and parsing methods as basis, design and realize a universal medical information integration and exchange service middleware. Experimental results show that the prototype system could perform medical information integration and exchange among relational database, HL7 and DICOM message, provide a feasi- ble scheme to solve the medical information island and lay a good foundation for establishing the unified medical infor- mation integration and sharing platform. The middleware has been applied in the project named ＂development and demonstration of opened medical information integration system＂.
