A methodology able to derive spatial geometric models from input sequences of sonographie slices is proposed. The developed modeling procedure can be utilized to perform computer-assisted anatomie 3D analysis both on all echo space and selected subregions. The modeling procedure is mainly composed of three sequential phases: a) automatic acquisition and preprocessing of time sequences of 2D echotomograms; b) 3D reconstruction of images and computing of discrete distance maps of selected echoes according to predefined projective laws; and c) generation of a spatial geometrie model of the examined object starting from the previously computed maps.
