Understanding the structure and morphology of the hepatic vessels and approximation of liver segments is important for liver surgical planning. In this paper, we present a method to determine the anatomical labels of the portal vein subtrees for the purpose of the liver segment approximation. We especially address the problems inherent in labeling the portal vein, which are that the patient often has variant intrahepatic portal vein anatomy and multiple portal subtrees are able to have the same label. The user of our system can interactively perform the labeling by repeating the division of the portal vein structures described as a graph into two parts. In each division, the user defines the position and orientation of a dividing plane with a margin space of a certain width. In the margin space, labeling is disambiguated based on the global position information of subtrees of the graph. In experiments, we evaluated the method using twelve CT data sets, from eleven of which the radiologist could successfully obtain appropriate labeling results within acceptable time. Further, we confirmed that the margin space was useful to stabilize the labeling results. |
