Scan Volume Placement Metrics.
| Metric | 5th % | Median | 95th % |
|---|---|---|---|
| 3D IoU | 0.46 | 0.69 | 0.85 |
| Axial IoU | 0.61 | 0.81 | 0.95 |
| Sagittal IoU | 0.53 | 0.73 | 0.89 |
| Coronal IoU | 0.6 | 0.78 | 0.92 |
| Distance (cm) | 0.9 | 2.7 | 6.6 |
| Volume Error (%) | −30 | 2 | 45 |
| Overlap (%) | 57 | 84 | 99 |
| RMSE (cm) | 0.9 | 1.9 | 3.6 |
Results from scan volume model trained with RMSE loss function. IoU: intersection over union, Distance: absolute distance between the model-predicted volume centers and the technologist-prescribed volume center. RMSE: Root-mean-squared error between all 5 scan volume placement parameters. 5th % and 95th % stand for the 5th and 95th percentiles of the distributions, respectively.
