【摘要】 为了更好地推广手术模拟系统，介绍了基于PC的骨科手术模拟系统的实现及应用 。系统使医生能从特定患者的CT图像重构出三维表面模型，并使用了面向术式的手术模拟交 互，改善了三维交互。通过手术模拟，医生在实际手术前可以选择合适的手术方案，从而降 低手术风险。更多还原

【Abstract】 An orthopaedic surgery simulation system based on PC is presented. T he techniques for design and implemention of this system are discussed. The syst em allows surgeons to reconstruct 3D isosurface model from specific patients CT image. To improve 3D interactive performance operation-oriented is presented. Th ough surgical simulation, surgeons can choose proper operative schemes prior to actual surgery, accordingly the risk of the operation could be reduced.更多还原
