This chapter presents an automatic approach to estimate optimal resected liver regions for oncologic surgery planning. Usually, resected liver regions are determined by selecting cut-points on the portal vessels on 3D simulation software. Since the liver has complex vessel structure, it is difficult for human to find optimal resected liver regions. To solve this problem, a tumor domination ratio (TDR) is proposed to find all portal vessels related to tumors. The TDR allows us to compute the ideal resected region, that is, all the perfusion territories related to the tumor. Moreover, some types of conditions such as the radius of vessels are considered for practical surgical use. The experimental results demonstrate that the resected liver regions of the proposed approach are much smaller than those of the conventional approach in most cases.
