Abstract:
1. A tomosynthesis method by illuminating an object by means of an x-ray source with a linear trajectory, the method comprising: moving the x-ray source and a planar detector having a set of lines of detecting pixels linearly in opposite directions along an x axis, the object being placed between the x-ray source and the planar detector, the planar detector being parallel to a plane (x, y), wherein a space is referenced by a three axis reference system (x, y, z), acquiring and processing information from the planar detector by means of a computer, the processing of said information comprising: formulating a reconstruction volume of the object into the form of N fanned out planes (P) formed between the linear trajectory of the source and a detecting plane parallel to the linear trajectory of the source, each fanned out plane of said N planes including the linear trajectory of the source; and performing anisotropic regularization on at least one fanned out plane (P).
