| Abstract(in English) | In the previous report, we proposed a multi-label graph-cuts based simultaneous segmentation algorithm for multiple organs which utilizes estimated shapes of organs. The performance of the shape estimation, however, is low in the case of gallbladder whose variation in shape and pose is large, resulting in poor performance of the graph-cuts based segmentation. This study proposes a conditional statistical shape model of an organ in which information correlated with the target organ is used as a condition. We aim to boost performance of shape estimation and organ segmentation by use of the proposed model. This paper presents results of applying the proposed model to simultaneous segmentation of neighboring four organs in a CT volume and report that the performance of the proposed model was superior to that of a conventional non-conditional model. |
