| 20100232670 | COMPUTERIZED IMAGING METHOD FOR A THREE-DIMENSIONAL RECONSTRUCTION FROM TWO-DIMENSIONAL RADIOLOGICAL IMAGES; IMPLEMENTATION DEVICE - A set of radio-opaque surface reference marks detectable by a surface sensor are disposed on the surface of the subject for acquiring three-dimensional or 3D surface images of the surface of the subject; with each radiological image acquired is associated a corresponding surface image acquired at substantially the same time; an iterative process is implemented including a phase of incidence angle calculation and a phase of deformation calculation according to an iterative process, intended to determine the relative positions of the radiological images and the surface images and to perform a positioning in the three dimensions of the radiological images by assuming an absence of deformation of the subject, and to determine and correct on the radiological images the deformations of the subject for the relative positions determined in the phase of incidence angle calculation, the criterion for stopping the iteration being based on the deviation between the 3D coordinates of the reference marks between two successive iterations. | 09-16-2010 |
