1. A method of processing an image of an object wherein: an X-ray tube is shifted on a path relative to the object, with the tube, for different places along the path of the tube, X-rays are emitted, crossing the object for a multiplicity of directions of emission, using an X-ray detector situated opposite the emitter relative to the object, pieces of X-ray image data are detected for each of the directions of emission, at least one standard projection image of the object is produced wherein the presumed suspect zones are represented by markers, from image data wherein the method comprises the following steps: producing, in a digital volume of markers, 3D markers representing presumed suspect zones of the object, re-projecting the 3D markers in the standard projection image.
