摘要:
将医院提供的二维断层图像序列转变为直观立体效果的图像，展现人体双下肢骨骼的三维结构与形态。结合模糊C-均值聚类算法和区域增长法对CT断层图像进行分割，提取图像中感兴趣的区域ROI，即骨骼区域，再对分割后的图像采用面绘制的方法进行三维重建。两种分割方法的结合使用能使分割结果更加准确，Marching Cubes算法进行三维重建能获得良好的骨骼观察视觉效果。该方法涉及到了数字图像处理、计算机图形学以及医学领域的相关知识，可实现医学CT图像的三维可视化，为骨科医学诊断提供了形象直观的技术方法
Abstract:
The three-dimensional reconstruction of normal leg CT data provided by hospital, display the three dimensional structure and form. Firstly,fuzzy C-means （FCM） clustering algorithm and region growing algorithm is used to find a region of interesting （ROI） and segment from the CT data. Secondly ,reconstruct the segmented images three-dimensionally by surface rendering method. The appli- cation of two segment algorithms can help to get more accurate bone segmentation. MC algorithm works well in three-dimensional reconstruction. The method is an important application of computer graphics and image processing in biomedicine engineering. The result indicates that the segmentation algorithms and three-dimensional reconstruction method applied in the experiment can achieve three-dimen- sional visualization effectively and provide a visualized technology for orthopedics medical diagnosis field
