摘要
我们利用电脑数字图像处理技术,建立了一个服务于正颌外科的电脑辅助设计系统——正颌外科电脑模拟手术系统,对患者的头颅 X 线定位片进行测量,为正位片提供71项点线距离、角度值和比例值,为侧位片提供68项测量值,并作出诊断;对患者的侧面彩色像进行模拟手术,预测疗效,并将手术移动的数据,量化地提出手术方案,提供临床使用。结果可通过激光打印机和视频打印机进行打印,所有操作可在20 min 内完成。
How easily to simulate the orthognathic surgery with high accuracy and good reliability and visually explain the prediction of surgery to the patient with maxillo- mandibular deformities remains a key focus in oral and maxillofacial surgery.A Comput- er Aided Simulation System for Orthognathic Surgery (CASSOS) was developed by means of the technique of digital image processing,with which a detailed analysis could automatically be performed,including 71 measurements of distance,degree and ratio for fromtal cepholograms and 68 measurements for lateral one with a computer aided diag- nosis.A quantitatively surgical simulation for prediction of operation could satisfactorily be done for the clinical use.All data and images were printed by laserjet and color video printer.All procedures were finished in 20 minutes.
