摘要： A set of digital two-dimensional projected images of an object is acquired for different positions of a camera rotating around an object. The projected images are calibrated into a volume containing the object and divided into voxels, the space coordinates of which are identified in a chosen calibration frame of reference. A pretreatment is applied on each acquired image in order to elaborate a rectified image having a predetermined spatial orientation selected as a function of a chosen specific axis of the calibration frame of reference, and an iterative algorithm of algebraic image reconstruction between each rectified image and the set of voxels is applied by successively treating the voxels in a predetermined order linked to the choice of said specific axis, which makes it possible to minimize the duration of reconstruction of the three-dimensional image.

摘要： A process for reconstructing a tridimensional image of an object moving with a substantially cyclic motion, for example the vessels of the human heart, in which, for an acquisition duration extending over several cycles of the movement of the object, an acquisitio of a plurality of initial digital radiographic images is performed using a snapshot apparatus rotating around the object. Initial images having the same temporal occurrence in the course of each cycle are selected respectively in successive cycles so as to form a group of images which is associated with this same temporal occurrence. Several different groups of initial images corresponding respectively to several different temporal occurrences are formed. An intermediate tridimensional representation of the object is reconstructed on the basis of each group of initial images and of an iterative image reconstruction algorithm. A law of spatial deformation between two intermediate tridimensional representations is formulated on the basis of the two intermediate tridimensional representations corresponding to two successive temporal occurrences, and a final tridimensional representation of the object is reconstructed on the basis of the initial images successively acquired, of the spatial deformation laws successively formulated and of an iterative image reconstruction algorithm.
