Smoothed Norm Regularization for Sparse-View X-Ray CT Reconstruction

Figure 3

The results of Shepp-Logan phantom study. In (a), (b), and (c), from left to right, the reconstruction images are FBP, TV regularization, and SL0 regularization, respectively. And the display window is . In (d), (e), and (f), the difference images between FBP, TV, and SL0 reconstructions and the ground truth are shown. And the display window is .
