Study of Surface Reconstruction Based on Contours of CT Image Slices

At present, there are two main types for medical CT image surface reconstruction: one is way of the slice contour, the other is voxel reconstruction, the former method is simple, easy for calculation and much classical computer graphics techniques can be used, the latter is related to complex computing. In this paper, image contours are extracted by active contour model, simplified by DP algorithm. Use Delaunnay splicing to construct triangulations for the sampled points of contours, finally surface of a human head are constructed through the surface fitting techniques.
