目的：实现客户端无需特定操作系统和硬件设备，即可以以纯净网页载体实现家庭网络条件下医学三维影像可视化浏览。方法首先，采用偏态处理模式，客户端仅用于提交浏览请求和下载服务器投影的“伪3 D”二维数据。其次，建立客户端伪3 D交互坐标／视角变换模型，结合JS＋HTML技术，实现客户端的伪3 D互动；然后，改进成熟的HTTP消息管理机制，实现客户端网页与服务器的即时通信。最后在30 kbps带宽下，分别使用iPad、PC和安卓手机对同一数据集（495帧249 MB）进行三维可视化浏览操作，验证其在较差家庭网络环境下，不同入网终端对该平台的可视化交互功能的支持情况。结果通过三种操作终端的在线测试可知，平台的Web通用性与操作准确性良好，历次操作反馈时间均小于1．5 s且画面更新流畅。结论通过较为极端的家庭网络环境测试，本设计无论反馈准确性和及时性均达到预定要求，能够满足可视化交互的要求，可以作为一种低成本的影像共享方式，服务于医护人员以即时获取医学影像信息。

Objective Client terminal of this can browse and share three-dimensional visualization medical images ( TDVMI ) based on Pure Web without specific operating system and hardware processing equipment.Methods First of all, we design the image processing work focused on the server side , and put its projection ‘pseudo 3D’ which is two-dimensional data online for clients to download and display in ‘3D’ effect.Second, we build client pseudo 3D interactive coordinates/perspective transformation model to achieve the client’s pseudo 3D interaction with JS&HTML technologies.Then, we improve the mature HTTP message management mechanism to achieve the client web pages with instant messaging and flicker -free updates. Finally, under 30 KBps, we respectively use the iPhone , android mobile phone , and PC to access the same data set (495 frames 249 MB) for 3D visualization browsing in order to test the effect with different access terminals.Results Through online tests of the three terminals , we know that the compatibility and accuracy of accessing medical images .
