Paper Abstract

In the field of liver surgery 3D, visualizations of the intrahepatic vessel systems and their relationship to tumors are of major interest for the preoperative planning. To achieve a fast and robust computer assistance with optimal quantitative and visual information, we present methods for a geometrical and structural analysis of vessel systems. Based on CT and MR scans the following steps are performed: (1) The volume data is preprocessed and the vessels are segmented. (2) The skeleton of the vessels is determined. (3) The skeleton is transformed into a graph enabling a geometrical (radii, length of branches) and structural (ramifications, hierarchy) shape analysis. Using this information the different intrahepatic vessel systems are identified automatically. Interactive measuring of length, volume and diameter of vessels is supported. Also the devascularized territories of the liver due to tumor resections can be estimated. The methods have been evaluated in the clinical environment in more than 120 cases so far.
