This paper presents a method for the quantitative analysis of the left ventricle mobility, based on the development of a 3D deformable dynamic model. The model is a superquadric-one with different parametric deformations, The data input far the adjustment of this model is a sequence of volumes of the left ventricle obtained in an echocardiography test. An electromechanical device controlled by the computer is adapted. This allows the acquisition of 60 slices in a rotational 3D symmetry. A specialist cardiologist segments the volumes. An objective function is defined to the adjustment of model parameters, The energy of the error is minimized,when the parameters are adjusted using a similar focus to the training of the pack Propagation neural network. The dynamics of the, position, orientation, size, torsion and its shape have been recovered from the model. This focus permits the obtaining of results clinically useful. If we compare quantitatively the volume of the left ventricle and the volume of the developed superquadries, in function of time, a small error around 1% is observed in the volume calculation, Therefore, we can conclude that deformable superquadric captures the global parameters of the left ventricle.
