摘要

本文提出了一种交互式实时三维分割方法。不像通常的二维切片分割，我们直接对三维图像进行体分割，将快速前进算法扩展到三维。提出了快速行军法中种子点的设置和速度的构造等关键步骤。然后显示各个解剖器官(肺、气管)的三维分割结果，整个分割过程仅需几分钟。

An Interactive Real Time Segmentation Method for 3D medical image

In this paper an interactive real time 3D segmentation method is presented. Not as the usual slice by slice segmentation in 2D, we perform volumetric segmentation on the 3D image directly, by the extention of fast marching algorithm to 3D. The key steps that set seed points and construct velocity in the fast marching method are put forward. Then 3D segmentation results are show in various anatomical organ (lung, trachea), and the whole segmentation procedure takes only several minutes.
