Introduction In the last decades there was a growing interest in designing CAD devices for medical imaging the main role of these system is to acquire the images generally TAC or RMI and to display the parts of interest of human body on suitable visual devices after some pre-elaboration steps aimed to improve the quality of the obtained images. A TAC or a MRI sequence obtained as a result of a scan process of the interested parts of the human body is a generally wide set of 2D gray-level images seen as the projection of the body into three different coordinate planes. Starting from these sequences it is rather difficult for the radiologist to imagine the whole appearance of the body parts since without a 3D model of each part it is only possible to browse the images in the three planes independently. In this framework the most challenging task remains that of extracting from the whole images a 3D model of the different parts such a model would be important not only for visualization purposes but also for obtaining quantitative measurements that could be used as an input to the diagnostic process. Even if the pre-processing step of the acquired images plays a key role in the achievement of a good visualization quality the literature is today so rich of papers describing procedures aimed to increase the signal noise ratio that this problem can be now considered as definitely solved. So the attention of researchers is nowadays concentrated on the definition of robust methods for the 3D segmentation. In the case of Magnetic Resonance Images MRI the segmentation is made complex by the unavoidable presence of inhomogeneity in the images as well as the presence of image distortions. Despite the research efforts and the significant advances achieved in recent years .
