Technique of 3D virtual surgery based on medical images / 中国医学影像技术

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.
