Abstract(in English) This paper proposes a method of interactive segmentation of pancreases from abdominal CT images based on the anatomical knowledge of medical doctors as well as the statistical information of pancreases. This method is composed of two phases: training and testing. In the training phase, pancreas regions are manually extracted from sample CT images, and then a probabilistic atlas of pancreases is constructed. In the testing phase, a medical doctor selects seed voxels for a pancreas and background in a test image. The probabilistic atlas is transformed by using a Homography matrix so that the transformed atlas and the seeds are fitted as much as possible. The graph cut technique whose data term is weighted by the probabilistic atlas is applied to the test image. This doctor-in-the-loop segmentation method is applied to actual abdominal CT images, and experimental results are shown.
