Quantitative comparison of different reconstruction methods based on $\text{Sim}\left({\mathbf{y}}_k^i,{\mathbf{A}}_k^i{\mathbf{x}}^i\right)$ after the final SVR-SRR iteration ($i=3$) in terms of SSIM and PSNR. A * denotes a significant difference compared to SRR (M) within each group based on Kruskal-Wallis with post-hoc Dunn tests $\left(p<0.05\right)$. Thus, SRR (S) and SRR (M) appear of similar volumetric self-consistency as quantified by the similarities between motion-corrected and respectively projected high-resolution volume slices.
