JSover: Joint Spectrum Estimation and Multi-Material Decomposition from Single-Energy CT Projections
JSover jointly reconstructs material volume fractions and the X-ray spectrum from single-energy CT projections using a spectrum library and an implicit neural network, reducing beam-hardening errors compared with two-step image-domain decomposition.
