基于WADO的医学影像浏览系统研究与设计

摘要

目的：解决目前区域医疗、远程会诊和移动医疗等对Web下访问医学影像的需求问题。方法采用WADO技术（用于医学图像的传输和显示的技术）和URI（资源标志符）技术实现B/S架构的医学影像浏览系统。该系统基于DICOM标准，浏览器端通过HTTP方式请求要查看的医学影像， Web服务器端通过公共网关接口（CGI）技术实现医学影像处理并返回JPEG格式影像，客户端浏览器收到影像后进行显示。结果通过在Windows的IE、Firefox、Google Chrome、Apple Safari等主流浏览器上进行测试，系统均可以顺利运行。结论该系统与操作系统、浏览器版本无关，是跨操作系统、跨浏览器的医学影像浏览系统。%Objective To cope with the regional medical, remote consultation and mobile medical problems in Web access to medical images.Methods With adoption of WADO-URI (Web Access to DICOM Objects- Uniform Resource Identifier) technology, a medical image viewing system was constructed based on the B/S (Browser/Server) architecture. In line with the DICOM (Digital Imaging and Communications in Medicine) standard, the request of viewing medical images was sent out by the client browservia HTTP (Hyper Text Transfer Protocol). Then, the Web server realized the medical image processing through CGI (Common Gateway Interface) technology and returned with the JPEG format images. The images would be displayed after receipt.Results According to the test results, the system had proven its successful operation in Windows IE, FireFox, Google Chrome, Apple Safari and other mainstream browsers. Conclusion Being independent with the operating system and browser version, the system was a medical image viewing system across multiple operating systems and browsers.
