摘要
目的构建人体腕骨解剖计算机辅助模拟系统（3DCACAS），实现腕骨三维分割、腕骨解剖、诊断分析、手术设计、疗效评价和三维测量。方法系统基于Windows XP，使用Microsoft Visual C＋＋开发平台，借助OpenGL辅助开发工具。采用优化的Marching Cube（MC）算法，以CT数据进行三维重构，OpenGL工具进行三维显示与控制。采用基于空间的方法进行三维局部分割。通过像素叠加进行三维量化处理。结果建立了人体手腕骨解剖计算机辅助模拟系统，功能包括图像三维真实感显示、三维分割、三维测量以及腕骨手术内置固定钢板辅助设计。结论3DCACAS的建立，为研究手腕骨运动学改变、诊断腕关节疾病的病理变化及腕骨手术术前计划提供了参考。
Objective To design and construct a 3-dimensional carpal anatomy computer-aided simulation system （3DCACAS） which can realize three-dimensional segmentation and anatomical dissection of the carpal, diagnose and analysis, surgical design, outcome evaluation and 3D measurement. Methods The software ran on Windows XP operating system, was developed with Microsoft Visual C ＋ ＋ platform and was in virtue of OpenGL. In the system, optimized Marching Cube（MC）was used in 3D reconstruction. 3D display and control was designed by OpenGL. 3D arbitrary region segmentation was realized by spatial segmentation and pixels superimposition was used in 3D measurement. Results A computer-aided surgical simulation system for carpal anatomy was developed. Its functions included 3D reality display of images, 3D segmentation, 3D measurement and computer-aided surgical design of internal fixation of the carpus. Conclusion The construction of 3DCACAS provides a reference for studying carpal kinematics, diagnosing pathological changes of carpal ailment and planning surgeries around the carpus.
