3-D deformable model for abdominal aortic aneurysm segmentation from CT images

In this paper we propose a technique for 3-D segmentation of abdominal aorta computed tomography (CT) images. Output data of the proposed algorithm is a 3-D model of aorta that can be used for measurement of aortas dimensions. Thos information are very important in minimally invasive treatment of abdominal aortic aneurysm. The technique is based on deformable model. The deformable model is implemented using a level-set algorithm for implementation of the method. The level set algorithm has several advantages over classical “snake” algorithms. Experiments have been performed using real patient CT angiography images and have shown good results.
