摘　　要：目的计算机辅助建立髋关节可视化三维解剖模型为影像诊断学和虚拟外科手术提供形态学资料。方法选取30例患者,对其髋关节进行螺旋CT扫描,扫描数据以Dicom3.0格式直接导入计算机图形图像工作站,进行精确勾画及三维体素重建。结果三维重建模型能清楚显示髋关节骨性结构的毗邻空间关系,完整显示了髋关节及骨髓腔等的轮廓及内部细节并能在三维空间内能够任意角度旋转观察。结论计算机辅助髋关节三维重建和可视化可全面准确重现髋关节三维立体形态和空间关系,为进一步研究有限元生物力学研究、髋关节假体设计及虚拟植入等提供基础。Objective To establish digitized 3-dimension（3D）visible model of hip joint with computer assistance to provide morphological data for image diagnosis and hip virtual surgery.Methods Thirty cases of hip pain were scanned with helical CT and the images were rebuilt with bone 3D reconstruction in computer workstation.Results The three-dimensional reconstruction images can reveal the spatial relationship adjacent to the bones distinctly and perfectly.The visualized reconstructions of hip can be presented individually or jointly.Conclusion Hip joint computer assisted three-dimensional reconstruction and the digitized visible model can display the stereo and spatial relations completely and accurately.
