Reconstructed images from truncated dead mouse dataset with 11 sources in a display window [0, 0.34]. From top to bottom in the left panel, the images were reconstructed from full-scan, half-scan and one-third-scan, respectively. From left to right, the images were reconstructed by the classical FBP method, TVM-SD method after 60 iterations (5 TV minimization loops in each main loop), and TDM-STF method after 60 iterations (5 soft-threshold filtering loops in each main loop), respectively. And the right panel shows image profiles along the horizontal central lines in the left panel, respectively.
