This paper proposes a method of interactive segmentation of pancreases in abdominal CT images based on the anatomical knowledge of medical doctors as well as the statistical information of pancreases. Pancreas regions are manually extracted from training images, and then a probabilistic atlas whose voxel values represent the probabilities of a pancreas is generated. A user (a medical doctor) sets seed regions for a pancreas and background of a test image. The probabilistic atlas is translated so that the atlas and the seed regions are overlapped as much as possible. The graph cut technique whose data term is weighed by the probabilistic atlas is applied to the test image. These processes are iterated. This doctor-in-the-loop segmentation method is applied to actual images, and experimental results are shown. |
