A CT Reconstruction Algorithm Based on Non-Aliasing Contourlet Transform and Compressive Sensing

Compressive sensing (CS) theory has great potential for reconstructing CT images from sparse-views projection data. Currently, total variation (TV-) based CT reconstruction method is a hot research point in medical CT field, which uses the gradient operator as the sparse representation approach duri...
