我们提出了一种新的体可视化方案，上下文为基础的体可视化，以协助外科医生在手术计划。该可视化方案与普通的基于表面的渲染和体渲染不同，它提供了一个将基于表面的渲染和体渲染结合起来的框架，联合收割机。我们可以同时实现基于面绘制强大的操作能力和体绘制一样好的绘制效果。该可视化方案采用一种特殊的数据结构化段树来管理可视化场景，其中包括所有需要可视化的体对象和图形对象（手术工具），为图形对象和体对象提供了一个基于上下文的通用接口，通过该接口，我们可以以相同的方式轻松地控制图形和体对象。基于上下文的可视化方案可以通过选择性地重新可视化受影响的对象来更快地生成场景，从而大大提高体可视化的性能。在此基础上，我们在WinNT平台上，利用OpenGL 1.1和VolumePro vg 500开发卡，实现了一个交互式的手术计划系统--虚拟医生。该系统是一个很好的三维体视化工具和增强现实系统的交互式手术规划和进一步研究在这一领域。
We present a new volume visualization scheme, context based volume visualization to assist the surgeon in surgical planning. This visualization scheme differs from ordinary surface based rendering and volume rendering by providing a framework to combine surface based rendering and volume rendering. We can achieve the powerful manipulating capability of surface based rendering and as good a rendering effect as volume rendering at the same time. Using a special data structured-segment tree to manage the visualization scene, which includes all the volume objects and graphics objects (the surgical tools) needed to be visualized, this visualization scheme provides a common context based interface for both graphics objects and volume objects, through which, we can control graphics and volume objects easily in the same way. The context based visualization scheme can greatly increase the performance of volume visualization by generating the scene much faster through selectively revisualizing the affected objects. Based on these ideas, we implement an interactive surgical planning system, Virtual Doctor based on OpenGL 1.1 on WinNT platform and VolumePro vg500 card. This system is a good 3D volume visualization tool and augmented reality system for interactive surgical planning and further research in this area.
