| Abstract(in English) | This paper presents an automated metastatic liver tumor segmentation process from plane and portal venous CT volumes. First we propose an automated segmentation method based on shape constrained graph cut algorithm to extract sidewall of body cavity, diaphragm and liver. Multi phase CT volumes provide helpful information in diagnosis. However, it is difficult for a single process to use the information effectively. We have aimed to develop an accurate process by combining many weak segmentation processes using a boosting algorithm. This paper shows the results of evaluating these algorithms by cross-validation using 20 set of CT volumes. |
