摘　　要：基于计算机的外科手术仿真系统已被广泛用于医疗教育、手术训练、手术计划,还被作为术中的辅助手段。随着具有力反馈设备在虚拟膝部手术中的应用,拓展了体数据可视化技术在医学实践中的应用范围,使医务人员不但能看到而且可以触摸并可以使用各种虚拟手术器械对三维虚拟人体膝部进行切割,修补,嫁接等操作。该文介绍了虚拟膝部手术系统的组成部分,主要包括:图像数据的获取和分割,三维模型的重建及人机交互操作,并详细说明每一部分的技术要点及其所采用的方法。<Abstrcat>Computer-based surgical simulation has many applications in education and training, surgical planning, and intra-operative assistance. While the feedback devices have been used in virtual knee operation systems, they provide the quality of human-computer interaction by accommodating not only the sense of vision but also the sense of touch. The simulator allows surgeons to use various virtual surgical instruments to operate on virtual knee, such as cutting, prostheses and bone grafts. It extends the using of volume visualization in medical filed. In this paper, components of virtual knee system (including image acquisition and segmentation, 3D model reconstruction, human-computer interaction) are detailed and the key techniques of each part are introduced.
