| 摘 要： | 为了在计算机辅助虚拟手术中对重建的三维模型进行切割，提出一种医学图像三维表面模型切割算法，利用鼠标在模型上画任意形状的封闭曲线来模拟手术刀的切割轨迹，从而实现手术过程中的任意交互切割。仿真实验结果表明，该算法具有良好的交互性，能够获得较好的虚拟切割效果，具有一定应用价值。

| Abstract: | In order to cut the reconstructed 3D models in computer aided virtual surgery,a cutting algorithms for 3D surface model in medical images is proposed.By using the mouse to draw an enclosed curve on the model,the bistouries cutting orbit is simulated,which implements the arbitrary mutual cutting in surgery process.Simulation experimental results show this algorithm has better interaction,can obtain well virtual cutting effect,and has the values of application. |
