Method For Reconstructing An Object By X Ray Tomography, Comprising A Calculation Of Regularization Terms
Abstract: The invention relates to a method for reconstructing an object by x-ray tomography by means of x-ray sources and detectors. The method comprises the following steps: obtaining (EO) positions of the x-ray sources and detectors; pre-calculating (E1) a set of directions; calculating (E2) a tomographic incompleteness vector map; calculating (E3) a tomographic incompleteness map of the metrics IM(x); calculating (E4) regularization terms from the tomographic incompleteness vector map and from the tomographic incompleteness map of the metrics; and solving (E5), iteratively, a regularized tomographic reconstruction problem by means of the calculated regularization terms.
