Method for reconstructing a three-dimensional image of a moving object, in particular a three-dimensional image of the human heart vessels

In order to reconstruct a three dimensional image of an animated object a substantially cyclic movement is carried out during an acquisition period extending over several cycles of movement of the object, acquiring a plurality of images initial digital radiographic apparatus from a catch rotating around views of the object. respectively is selected in successive cycles, the original images having the same temporal occurrence during each cycle so as to form a group of images associated with the same temporal occurrence. Forming a plurality of different groups of initial images respectively corresponding to plural different temporal occurrences. Reconstructing from each group of initial images and an iterative algorithm for image reconstruction, a three-dimensional representation through the object. Is developed from two intermediate three-dimensional representations corresponding to two successive time occurences a law of spatial distortion between the two intermediate three-dimensional representations, and reconstructing a final three-dimensional representation of the object from the initial images successively acquired, laws deformation space successively developed and an iterative algorithm for image reconstruction.
