1. Method of reconstruction of a three-dimensional image of an object from a set of digital two-dimensional projected images of the object obtained for different positions around the object, comprising the steps of:

  • a. acquiring the set of digital two-dimensional projected images and a reconstruction of the three-dimensional image from the projected two-dimensional acquired images and an iterative algorithm of algebraic image reconstruction;

    b. calibrating the different position images for a volume containing the object and dividing into voxels, the space coordinates of which are identified in a chosen calibration frame of reference;

    c. applying a pretreatment on each acquired image in order to establish a rectified image having a predetermined spatial orientation selected as a function of a chosen specific axis of the calibration frame of reference; and

    d. applying the iterative algorithm of algebraic image reconstruction between each rectified image and the set of voxels by successively treating the voxels in a predetermined order linked to the choice of said specific axis, whereby a duration of reconstruction of the three-dimensional image is minimized.
