摘　　要： 虚拟手术是虚拟现实技术在医学领域的重要应用,可以用于术前对手术过程的模拟,提高手术的成功率,降低医疗成本。论述并设计了一种基于64排CT数据的肝胆虚拟手术系统,而且分别对该系统中图像分割、图像配准、3D可视化以及虚拟切割等关键技术进行了深入的探讨与研究。给出了手术刀虚拟切割肝脏及内部管道的实验结果,结果表明,该系统对制定合理的手术预案具有重要的临床价值。 Virtual surgery is the most important application of virtual reality in medical field. It can be used in many situations, such as simulating the process of surgery to increase the success probability and decrease the cost of surgery. A virtual surgery system of liver and gallbladder based on 64-row CT data was put forward, moreover segmentation, match, 3D-reconstruction and tissue deformation, which were the key technologies of virtual surgery system, were introduced. At last, some simulation results of bistouries and liver were proposed. The result shows that the simulation system is important in planning reasonable operation scheme.

关 键 词： 虚拟手术 图像分割 可视化 手术模拟
