基于虚拟现实的女性盆腔可视化及手术仿真

Visualization and surgical simulation of female pelvis based on virtual reality

目的实现基于虚拟现实的女性盆腔可视化及手术仿真。方法选取中国可视人体数据集的盆腔部分作为数据源,对盆腔中的重要器官进行分割处理,并在此基础上进行基于VRML的盆腔可视化以及基于Dextrobeam系统的虚拟手术仿真研究。结果成功构建了基于虚拟现实的女性盆腔网络化模型和手术模型,可清晰显示各盆腔器官结构,并进行手术仿真操作。结论虚拟现实技术的运用可有效地推动解剖教学与手术设计,为医学教育与培训提供逼真的模拟实践平台。

Objective To implement visualization and surgical simulation of female pelvis based on virtual reality. Methods The successive cross-section images of pelvic part from a Chinese Visible Human （CVH） dataset were adopted. The important organs in pelvis were segmented initially. Then the VRML based visualization and Dextrobeam-based virtual surgery simulation were carried out. Results A networked pelvic model and a surgical model were constructed with virtual reality techniques. The organs and structures in pelvis could be displayed clearly and the simulated surgical operations could be performed. Conclusion The application of virtual reality techniques can facilitate the anatomical teaching and surgery design. More significantly, a realistic practice platform will be provided for medical education and training.
