Parameter sensitivity analysis and ablation study. The top row (a-c) shows parameter sensitivity analysis of DPMA on the AAPM simulated dataset with 64 views: (a) the penalty parameter \(\rho\), (b) the primal step-size parameter \(\eta\), and (c) the regularization parameter \(\alpha\). (d) Validation curves of different loss combinations in terms of MSE, PSNR, and SSIM metrics, where \(L_S\) is the sinogram domain loss, \(L_R\) is the image domain loss, and \(L_I\) is the enhancement loss.
