Comparison between original planned dose distributions and delivered dose distributions.
| Average ± SD | Planned dose distribution | Delivered dose distribution | |
|---|---|---|---|
| CTV | D98% (Gy) | 11.7 ± 0.1 | 11.7 ± 0.1 |
| D95% (Gy) | 12.0 ± 0.0 | 12.0 ± 0.1 | |
| D2% (Gy) | 12.9 ± 0.1 | 13.1 ± 0.1 | |
| V110% (%) | 0.6 ± 0.1 | 1.6 ± 0.9* | |
| V90% (%) | 99.4 ± 0.4 | 99.6 ± 0.2 | |
| Lung | Mean (Gy) | 9.5 ± 0.1 | 9.5 ± 0.3 |
| V10 Gy (%) | 38.4 ± 1.7 | 37.8 ± 5.4 | |
| CTVbs | D98% (Gy) | 11.0 ± 0.4 | 10.5 ± 0.3 |
| D2% (Gy) | 13.1 ± 0.1 | 14.0 ± 0.6* | |
| CTVls | D98% (Gy) | 11.1 ± 0.2 | 10.8 ± 0.4 |
| D2% (Gy) | 12.8 ± 0.1 | 12.8 ± 0.1 | |
Delivered dose distributions mean the integration of the dose distributions for each actual irradiation.
