                         T-Surfaces model and isosurface genera-tion methods in a general 
                         framework for surface reconstruction in 3D medical images. 
                         T-Surfaces is a deformable model based on a triangulation of the 
                         image domain, a discrete surface model and an image threshold. Two 
                         types of isosurface generation methods are considered: the 
                         continuation ones and the marching ones. The former is useful 
                         during the reparameterization of T-Surfaces while the later is 
                         suitable to initialize the model closer the boundary. 
                         Specifically, in a first stage, the T-Surfaces grid and the 
                         threshold are used to define a coarser image resolution. This 
                         field is thresholded to get a 0-1 function which is processed by a 
                         marching method to generate polygonal surfaces whose interior may 
                         contain the desired objects. If a polygonal surface involves more 
                         than one object, then the resolution is increased in that region 
                         and the marching applied again. Next, we apply T-Surfaces to 
                         improved the result. If the obtained topology remains incorrect, 
                         we enable the user to modify the topology by an interac-tive 
                         method based on the T-Surfaces framework. Finally, we demonstrate 
                         the utility of diffusion methods for our approach.",
