Nonconvex prior image constrained compressed sensing (NCPICCS): Theory and simulations on perfusion CT

Purpose: To present and evaluate a new image reconstruction method for dynamic CT based on a nonconvex prior image constrained compressed sensing (NCPICCS) algorithm. The authors systematically compared the undersampling potential, functional information recovery, and solution convergence speed of f...
