Inner product regularized multi-energy X-ray tomography for material decomposition
Salla-Maaria Latva-Äijö, Filippo Zanetti, Ari-Pekka Honkanen +4
Multi-energy X-ray tomography is studied for decomposing three materials using three X-ray energies and a classical energy-integrating detector. A novel regularization term compris…
