Table 3.
Comparison of the minimum CTV dose (in % of the nominal dose) among the static, average- and segment-based convolution plans in a single fraction and in 37 fractions (entire treatment course). The single-fraction plans incorporated the tracking data from the fractions with largest SD and mean; the plans delivered in 37 fractions incorporated the motion of the patient with largest overall SD
| Motion scenario | IMRT plan | Minimum CTV dose (% of nominal dose) | ||
|---|---|---|---|---|
| Static plan | Ave. conv. plan | Seg. conv. plan | ||
| Fraction with largest motion variation (SD) | 1 | 98.2 | 97.2 | 92.8 |
| 2 | 98.1 | 95.8 | 93.2 | |
| Fraction with largest mean motion | 1 | 98.2 | 86.0 | 86.0 |
| 2 | 98.1 | 83.3 | 84.8 | |
| Patient with largest motion variation (SD) | 1 | 98.2 | 97.3 | 97.3 |
| 2 | 98.1 | 97.2 | 97.0 | |
