| Abstract(in English) | The normal anatomical structure recognition is very useful and necessary in computer-aided diagnosis system. This study proposes a method for automated generation of probabilistic atlas of liver region using non-contrast torso CT images which is a new approach for anatomical structure recognition in CAD development. In order to generate a precise probabilistic atlas, normalizing the anatomical structures in different patient cases is very important. We developed a new method to normalize the liver positions and shapes based on diaphragm deforming and create a particular probabilistic atlas for a patient dynamically and automatically. A fully-automated atlas-based liver segmentation method is developed and evaluated with a lot of CT images finally to show the validation and usefulness of the generated probabilistic atlas for CAD development. |
