| Abstract(in English) | A fully automated method is described for segmentation and anatomical labeling of the abdominal vessels from contrast-enhanced CT data of the upper abdomen. By assuming that the regions of the organs and great vessels have already been automatically segmented, the problem is formulated as extracting and selecting the optimal paths between the organ and great vessel regions based on a basic anatomical constraint that vessels supplying blood to an organ consists of tree structures whose root nodes are located in the great vessel region and leaf nodes in the organ region. Using the constraint, the proposed method solves both of vessel segmentation and anatomical labeling. In addition, the method is robust against topological variability of the branching patterns. Experimental results using 10 datasets demonstrate that the proposed method was effectively applied to several kinds of the abdominal arteries. The average F-measure was 0.89 for proposed and 0.74 for previous methods. |
