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

Figure 4

The results of human head slice simulation study. In (a), (b), and (c), from left to right, the reconstruction images are FBP, TV regularization, and SL0 regularization using noiseless projections. And the display window is  HU. In (d), (e), and (f), the corresponding reconstructed images with simulated noisy projection data are shown. And the display window is  HU.
