3D Alternating Direction TV-Based Cone-Beam CT Reconstruction with Efficient GPU Implementation
Iterative image reconstruction (IIR) with sparsity-exploiting methods, such as total variation (TV) minimization, claims potentially large reductions in sampling requirements. However, the computation complexity becomes a heavy burden, especially in 3D reconstruction situations. In order to improve...
