From: Bone-induced streak artifact suppression in sparse-view CT image reconstruction

Contrast phantom images reconstructed by the iterative methods. Three iterative reconstruction methods, a ART, b CS and d SAS-CS, have been used. The soft tissue image c has been reconstructed in step 5 of SAS-CS. The images are normalized to 1.0. The display window is [0.05 0.45].
