Table 5. Mean Image Quality Assessment Ranking of Image Reconstruction Methods.
| Reconstruction Method | DLA-1 | DLA-2 | DLA-3 | ADMIRE | FBP |
|---|---|---|---|---|---|
| Image noise | 1.1 (0.2)*† | 1.9 (0.2)*† | 3.2 (0.4)† | 3.8 (0.4) | 5.0 (0) |
| Spatial resolution | 4.8 (0.5)*† | 4.0 (0.3)* | 1.8 (0.7) | 1.8 (1.1) | 2.6 (0.9) |
| Overall image quality | 4.6 (0.6)* | 3.7 (0.7)* | 1.4 (0.5)† | 1.7 (0.7) | 3.7 (0.9) |
Data are mean ranking score (standard deviation). *p < 0.05 in pairwise comparison with ADMIRE, †p < 0.05 in pairwise comparison with FBP.
