The comparison between reconstructed images using three different reconstruction algorithms and original Shepp-Logan image. (a) The profiles of line 128 in reconstructed images using ART and ART-TV methods from noise-free data and original Shepp-Logan image, (b) the profiles of line 128 in reconstructed images using SpBr- methods from noise-free data and original Shepp-Logan image, (c) the profiles of line 128 in reconstructed images using ART and ART-TV methods from noise data and original Shepp-Logan image, and (d) the profiles of line 128 in reconstructed images using SpBr- methods from noise data and original Shepp-Logan image.
