Inner product regularized multi-energy X-ray tomography for material decomposition
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 …
