This paper introduced a combination utilization of multi-mathematical morphology algorithms to realize the extraction of abdominal organ and its relative blood vessels. This paper first combined compound mathematical morphological gradient algorithm with conditional dilation algorithm to extract organs. Then, it applied multi-dimension structure Top-Hat algorithm and Threshold Value for the extraction of relative blood vessels. At last, used recursive erosion algorithm and geodesic influence for separating touched organs. Those methods above are quick for extracting, and the organs and blood vessels' extraction effects are good.
