计算机成像技术模拟颅面三维手术研究

Study on three-dimensional virtual surgical craniofacial surgery simulation

目的:应用计算机三维成像技术,开发建立计算机三维模拟手术系统,在计算机屏幕"手术室"中完成正颌外科骨切开手术。方法:将手术前牙颌面畸形患者CT断层序列图像重建成三维体数据,通过表面绘制的方法显示出三维图像,进行骨组织的切割、旋转和平移等操作,以动画方式模拟全部手术过程并预测手术效果。结果:该系统直观地反映了手术过程和效果,便于医患交流,选择合理的手术方案。结论:颅颌面骨组织三维手术模拟系统具有较强的可视效果,对于提高手术的安全性和准确性具有重要作用。

Objective: Using computer to simulate orthognathic surgery and help surgeons to make effective surgical planning.Methods: Reconstruct preoperative CT slices to volume data and generate last 3-D visualization, Surgeons can perform virtual osteotomy, rotation and translation operations on bone tissues.Results:This system can simulate the process of surgery and postoperative effect. Conclusion: This system can help surgeons to make preoperative prediction and select reliable program to improve the reliability and effects for orthognathic surgery.
