基于医学图像的三维模拟手术

Technique of 3D virtual surgery based on medical images

目的对实现三维模拟手术的关键技术进行研究,构建基于医学图像的三维模拟手术平台。方法在VC++平台下,使用三维分割算法对体数据进行分割,结合VTK对读入的体数据进行交互式三维重建和虚拟切割,并对各种虚拟切割方式的性能进行分析。结果实现了医学CT/MR图像的交互式三维重建、虚拟手术刀切割以及虚拟手术规划。结论该系统可以辅助医生对手术过程进行模拟,为医生观察三维人体组织器官结构及病灶部位,实施辅助手术提供有力的帮助。

Objective To research the key technique in the virtual surgery,and to build a 3D virtual surgical system for medical imaging.Methods In VC＋＋ platform,the volume data were segmented by using a 3D segmentation algorithm.The 3D reconstruction and virtual cutting were achieved with the help of VTK,and the performance of the varied cutting methods was analyzed.Results The interactive 3D reconstruction,virtual scalpel cutting and virtual surgical planning of the medical CT/MR images were realized.Conclusion This system offers great help for doctor to simulate the operative process,to observe the 3D models of human organs and to carry out the computer-aided surgery.
