Table 3:
Quantitative analysis of the total MNSE, decomposed into ππ© and π2, for the anthropomorphic breast phantom images acquired at the LD (at a dose reduction factor of 50%) and at the FD. Also, the results for the restored images generated by neural network with the loss function: MSE, MAE, SSIM, PL1 to PL4, adversarial loss with different Ξ»adv, FID and for the model-based (MB) restoration method Confidence interval is shown for p-value=0.05.
