Abstract
A method of calibration for reconstructing three-dimensional models from images obtained by a tomography apparatus comprising a radiation detector and an X-ray source which can move with respect to the detector. In the method a set of markers are placed in the field of the X-rays and the positions of the projections of the markers onto the images acquired are processed so as to deduce from this the position of the source at the time of acquisitions, the markers being carried by one and the same support. The markers are fixed with respect to the support and the positions of the projections of the markers onto the images acquired are processed so as to deduce from this the position of the markers in space.
