| Abstract | In pre-operative planning for partial liver transplantation, the total liver volume must be virtually segmented from a setof CT scanned images. The liver, consequently, is divided into eight segments according to Couinaud's classification usinghepatic and portal veins as clues. To facilitate the visualization of the segmented liver model, we propose a computerizedprocess using four 3D plane cuts and cubic B?zier curve. In our experiments, fifteen liver volumes were used, and each of themwas cut into eight segments using our program and their average percentage volumes were analyzed. The results were inagreement with the ground truth. Our program is semi-automatic. It requires minimal user interactions. As a result, the user caneasily view the segmented liver model in both 2D and 3D perspective |
