TABLE 3.
Values for the geometric and HU‐agreement metrics between deformed computed tomography (dCT) and synthetic CT (sCT)
| Cases | ME (HU) | MAE (HU) | DSCbone (%) | DSCfat (%) | DSClung (%) |
|---|---|---|---|---|---|
| Abdominal (N = 63) | 8 (13) | 56 (7) | 47 (7) | 58 (4) | 82 (15) |
| Pelvic (N = 48) | –4 (1) | 45 (5) | 64 (4) | 57 (3) | – |
| All (N = 111) | 8 (10) | 49 (10) | 55 (12) | 60 (5) | – |
Note: Values are given as averages (one standard deviation). DSClung was calculated only for the abdominal cases.
Abbreviations: DSC, Dice similarity coefficient; MAE, mean absolute error; ME, mean error; N, the number of the dCT–sCT‐pairs per set.
