Mean doses for partially in-field organs from DVHs calculated by the TPS and the retrospectively adjusted mean doses computed assuming dosimetric errors of+60% and −60% for all portions of the DVH with dose less than 5% of the prescribed dose.

Organ: calculation method Mean dose (Gy/GyRx) Difference from DVH TPS-calculated mean
Spinal cord: TPS 2.35 × 10−1 –
Spinal cord: adjusted +60% dose error 2.40 × 10−1 1.8%
Au: Spinal cord: adjusted −60% dose error 2.33 × 10−1 1.1%
Esophagus: TPS 1.87 × 10−1 –
Esophagus: adjusted +60% dose error 1.88 × 10−1 0.8%
Esophagus: adjusted −60% dose error 1.86 × 10−1 0.5%
Left kidney: TPS 0.52 × 10−1 –
Left kidney: adjusted +60% dose error 0.61 × 10−1 17.3%
Left kidney: adjusted −60% dose error 0.46 × 10−1 11.5%
Lungs: TPS 0.57 × 10−1 –
Lungs: adjusted +60% dose error 0.59 × 10−1 3.5%
Lungs: adjusted −60% dose error 0.56 × 10−1 1.8%
