| 摘 要： | 为了给可视化虚拟人体模型的建立探索一种精确的重建方法和显示手段,同时也为医疗工作者提供一种更为细致、完全和快捷的观察方案,利用3D Slicer软件实现鼻部解剖结构的三维可视化。分别对单层切片进行感兴趣区的轮廓提取,将处理后的体数据导入3D Slicer,选择阈值进行进一步的图像分割,产生感兴趣区的标志图(labelmaps),并根据标志图重建出组织的三维表面模型;还可以显示不同结构之间的毗邻关系与空间定位。结果表明,基于CT图像和用3D Slicer软件对鼻部解剖结构的三维重建是有效的。

| Abstract: | The main purpose of this study was to develop a new reconstruction method for the development of Chinese Visual Human Project and provide a more accurate, complete and facilitated way to 3D view for medical workers. This study used the software 3D Slicer to reconstruct the anatomical structures of human nose. We extracted the contour of the ROI (Region of Interest) in each single slice and added the processed volumes into 3D Slicer. The output of the segmentation process was a set of label maps of the ROI. Based on the label maps, we could reconstruct the 3D surface model of the interested tissue. The result shows that this method may be used for the reconstruction of nose. |
