睁眼数字化面模在眶缺损仿真修复中的应用

目的:建立睁眼面部三维数字化模型,实现单侧眼眶部缺损的计算机仿真设计。方法:采用位相测量轮廓技术直接对患者面部三维轮廓信息进行采集,重建缺损面部睁眼的三维数字化模型。在Geom agic实体构造软件中,利用健侧眼眶部组织数据经镜像反转获得缺损区睁眼状态的三维实体数据。结果:完成了单侧眼眶部缺损面部组织的三维重建,获得了修复缺损区眼眶组织的三维实体数据并达到对称、逼真的设计效果。结论:应用位相测量轮廓术和逆向工程软件进行单侧眼眶部缺损修复的计算机辅助设计是一种切实可行的方法。

Imitating the restoration of orbital defect by a digital face model in condition of open-eyes

Objective:To build 3D digitized face model of unilateral orbital defect and to realize imitating design of defect section.Methods:Phase measuring profilometry was employed to acquire a 3-D digitized face model with open eyes.By Geomagic software,the image of normal orbit was extracted and mirrored with the image of the deformed side of the orbit.Results:A 3-D digitized face model of unilateral orbital defect was successfully reconstructed and 3-D normal orbit data of defect section was acquired.Conclusion:The use of phase measuring profilometry and RE software is a convenient and effective method to the computer-aided design for the restoration of unilateral orbital defect.
