摘要
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.
