摘　　要：目的:应用Java技术开发一个基于Web技术的操作简易、通用性强的医学图像发布环境。方法:采用Web服务器来查询和提取存储在DICOM服务器中的医学图像,客户端使用嵌有Java Applet小程序的Web浏览器来访问Web服务器,完成客户端对服务器端医学图像的提取,Java Applet小程序利用Web浏览器实现其图像操作。结果:我们使用Java技术开发一个基于Web技术的医学图像发布环境,完成了客户机通过Internet对服务器端医学图像的读取操作,实现了异地专家的在线交流。结论:与大多数传统的PACS相比,基于Web技术的PACS系统易于安装和维护,与运行平台无关,可以高效的显示、处理医学图像,容易和使用Web技术构建的PACS系统整合。设置适当的安全防范措施,用户可以在医院外部实现对该系统的访问。Internet技术的简易性和可扩展性使得该系统与传统PACS系统相比有着更大的优越性。Objective： An easily manipulated and flexible radiologic image distribution environment was developed with the help of Java technology. Method： This approach involves a Web server that allows the query and retrieval of images stored in a Digital Imaging and Communications in Medicine （DICOM）archive. The images can be viewed inside a Web browser with use of a small Java program known as the Applet Viewer, which is executed inside the browser. Results： A radiologic image distribution environment was developed with the help of Java technology, images retrieved from DICOM archive can be viewed and manipulated in the Web browser through the Intemet, Specialist from different hospitals can communicate with each others on line. Conclusion： The system offers several advantages over more traditional picture archiving and communication systems （PACS）：It is easy to install and maintain, is platform independent, allows images to be manipulated and displayed efficiently, and is easy to integrate with existing systems that are already making use of Web technologies. The system can easily be used from outside the hospital if a security policy is in place. The simplicity and flexibility of Intemet technologies makes them highly preferable to the more complex PACS workstations.
