Rat pelvic floor images reconstructed by the iterative methods. Three iterative reconstruction methods, ART (a), CS (b) and SAS-CS (c), have been used for 100-view imaging. The images are normalized to 1.0. The display window is [0.01 0.55]. Difference images taken from the reference image are shown in the bottom row. The display window is [-0.25 0.25] for the difference images.
