| 摘 要： | 目的利用髋臼轮廓的三维数据值重建髋臼骨形态,并能对其解剖结构进行定量测量。方法选取成人髋臼标本,通过CT扫描、图像边界处理和定标,利用CAD软件直接拟合出髋臼骨形态。结果重建的髋臼能客观反映髋臼真实解剖形态。结论以CT二维图像为依据,采用CAD软件,能准确地进行髋臼的重建,为髋臼的形态学研究提供了一种可行的方法。

| Abstract: | Objective To set up three-dimentional reconstruction of acetabulum bone structure from CT scanned image in computer with sofeware of CAD. Methods CT images of 40 normal adult boney acetabula were obtained and processed with the algorithm of histogram-threshold segmenting and Kirsh boundary detection to get a binary contour image.The contour of scanned acetabulum were then used for three-dimentional reconstruction with CAD software. Results The computerized 3-Dreconstuction of acetabulum bone structure appeared to mimic the real anatomy of acetabulum. Conclusion Methods proposed in this paper can be used with high accuracy and reliability for further scientific study. |
