摘　　要：利用HTML5标准集成的WebSocket和Canvas协议在网页进行事件交互、主客户端双向通信、图形图像绘制,结合VTK三维可视化工具包,研究在纯净Web中进行远程医学影像重建和交互的可行性并进行实验。提出以服务器为中心的建模思想,使大数据无需下载至客户端建模,避免了客户端因三维渲染而产生的硬件配置和初始网络传输压力,实现了远程医学影像三维重建交互与Web的无缝集成,并可适用于低配置计算机和移动设备。最后使用一组DICOM影像对该方法在因特网中进行测试,达到实时效果,这种能够跨越上网终端和设备性能限制的Web三维可视交流系统在医学远程辅助上具有较大意义。Integrating visualization toolkit and the capability of interaction,bidirectional communication and graphics rendering which provided by HTML5,we explored and experimented on the feasibility of remote medical image reconstruction and interaction in pure Web.We prompted server-centric method which did not need to download the big medical data to local connections and avoided considering network transmission pressure and the three-dimensional（3D）rendering capability of client hardware.The method integrated remote medical image reconstruction and interaction into Web seamlessly,which was applicable to lower-end computers and mobile devices.Finally,we tested this method in the Internet and achieved real-time effects.This Web-based 3Dreconstruction and interaction method,which crosses over internet terminals and performance limited devices,may be useful for remote medical assistant.
