According to the characteristics of medical images,a combinated algorithm of Live Wire algorithm and contour interpolation algorithm is proposed for 3D medical image segmentation.Compared with the original Live Wire algorithm,the improved algorithm greatly improves the performance of image segmentation without increasing complexity of the algorithm.And to make up the shortages fo the original algorithm,two measures are taken:(1) to find the shortest search path;(2) to reduce the search time complexity as far as possible.The improved algorithm and cosine interpolation contours are combined for the segmentation of cross-sectional image(critical layer) of lesions area where the shape changes evidently.Experiments show that the algorithm can segment the objects of interest from the sequence of medical images quickly and efficiently.
