Abstract:Multi-energy X-ray tomography is studied for decomposing three materials using three X-ray energies and a classical energy-integrating detector. A regularization term is used, which includes the inner products between the material distribution functions, penalizing any overlap of different materials. An interior point method is used to solve the underlying quadratic optimization problem; a previously developed preconditioner is extended to the case with three materials, while its theoretical properties are ana… Show more
