Abstract

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 ...
