method of reconstructing three-dimensional images on a mobile or deformable object

A method of tomographic reconstruction of three-dimensional images of an object such as the heart or other body from sets of measurements relating to a group of different states of the object. An approximate picture subject to each state (f |) is reconstructed from the associated measures and the movements of the object from a reference state to each of the states are evaluated (Dk) estimation of. image of the object in the reference state (f | ^ 0) is obtained by convergence to the real image by incorporating gradually the estimated image information relating to measurements and movements previously calculated from the object.
