In this paper, we propose an algorithm for the segmentation of medical image series based on the combination of the modified live wire algorithm and the contour interpolation algorithm.At the first, we modify the live wire algorithm by using fractional differential to construct the cost function., and then we do interactive segmentation of the key layers of medical image series;According to the consequence of segmentation, we segment the other images automatically by nonlinear contour interpolation algorithm;Finally, doing some reparation of the automatic segmentation result to guarantee the reliability of the result in interactive way.Experiment shows that this algorithm can obtain the boundary of the desired object from a series of medical image quickly and reliably with only little user intervention.
