本文旨在报道一种模拟正颌手术计划后三维面部软组织变化预测的新技术。提出了一种软组织变形方案--计算机辅助三维虚拟现实软组织规划与预测正颌外科（CASP）。手术计划是基于三维重建CT可视化。软组织变化预测两个新设计的算法：基于表面法线的模型变形算法和基于射线投影的模型变形算法。三维彩色人脸纹理映射技术也被用于生成彩色照片级真实感人脸模型。作为最终结果，可以从任意视点可视化预测和模拟的患者的彩色面部模型。
The purpose of this paper is to report a new technique for three-dimensional facial soft-tissue-change prediction after simulated orthognathic surgical planning. A scheme for soft tissue deformation, "Computer-assisted three-dimensional virtual reality soft tissue planning and prediction for orthognathic surgery (CASP)", is presented. The surgical planning was based on three-dimensional reconstructed CT visualization. Soft tissue changes were predicted by two newly devised algorithms: Surface Normal-based Model Deformation Algorithm and Ray Projection-based Model Deformation Algorithm. A three-dimensional color facial texture-mapping technique was also used for generating the color photo-realistic facial model. As a final result, a predicted and simulated patient's color facial model can be visualized from arbitrary viewing points.
