Statistical analysis for the ionization chamber array measurements.
| IC position | Mean | SD | abs. mean | abs SD | minimum | maximum |
|---|---|---|---|---|---|---|
| target volume | 0.3 | 1.5 | 1.2 | 0.9 | -2.7 | 3.7 |
| left penumbra | -13.3 | 2.3 | 13.3 | 2.3 | -15.8 | -10.5 |
| right penumbra | 7.8 | 0.1 | 7.8 | 0.1 | 7.8 | 7.9 |
| distal edge | -1.5 | 5.1 | 4.1 | 3.1 | -8.9 | 3.3 |
| position A | 0.8 | 1.6 | 1.4 | 1.0 | -2.5 | 3.7 |
| position B | -0.2 | 1.3 | 1.0 | 0.8 | -2.7 | 2.3 |
All values denote the relative dosimetric deviation between motion compensated and the stationary reference measurement in %. Position A refers to chamber positions indicated by solid lines, position B to chamber positions indicated by thin lines in fig. 1c.
