| Abstract(in English) | In this paper, we propose an extraction method of teniae coli from 3D abdominal X-ray CT images. It is important for a CT colonography CAD system to recognize anatomical structure of the colon. Teniae coli can be observed as three parallel curves on the colonic wall. They are one of important features that represent anatomical structure of the colon as well as haustra. Thus, we develop a method for extracting teniae coli from 3D abdominal X-ray CT images. Teniae coli are observed as sequences of ridge-breaks traversing haustra. The proposed method extracts haustra at first by computing curvature of colonic wall. Then, we extract teniae coli by analyzing extracted haustra positions. We applied the proposed method to six cases of successful haustra extraction. The experimental results showed that the proposed method could extract teniae coli satisfactorily haustra could be extracted correctly. |
