Image-domain multimaterial decomposition for dual-energy computed tomography with nonconvex sparsity regularization
Dual-energy computed tomography (CT) has the potential to decompose tissues into different materials. However, the classic direct inversion (DI) method for multimaterial decomposition (MMD) cannot accurately separate more than two basis materials due to the ill-posed problem and amplified image nois...
