基于PC平台的三维立体医学可视化系统

利用图形硬件的可编程性．实现了一套基于PC平台的高质量实时三维立体医学可视化系统．并在兼顾高质量和实时交互的前提下，将Phong模型体绘制光照、分类、非多边形等值面绘制及立体视觉等功能集成于系统之中。这套医学影像可视化系统已经在神经外科和整形外科得到应用．提高了外科诊断和手术计划的精确度。

A PC-Based 3D Stereoscopic Medical Visualization System

In this paper, a low-cost PC-based,high-quality and interactive 3D stereoscopic medical visualization system is presented, which can be clinically used for diagnosis and surgical planning. The algorithms of direct volume rendering have been improved for realization with the programmable graphics hardware under PC environment. Local illumination, classification and non-polygonal iso-surface rendering are also incorporated into the system in appropriate consideration of both high-quality rendering and real-time interaction. The medical visualization system has been applied to the neurosurgical and orthopedic planning and the effectiveness has been clinically proved.
