Learned Shrinkage Approach for Low-Dose Reconstruction in Computed Tomography

Figure 16

Upper row, left to right: reconstructions optimized for SNR values—FBP (28.5 dB), PWLS (30.6 dB), our method (31.41 dB). Lower row: reconstruction with higher spatial resolution—FBP (26.5 dB), PWLS (29.6 dB), our method (30.73 dB).
