Summary of the liver mean doses.
| Mean physical dose for the whole liver (Gy) | 14.8 (5.34–35.93) |
| Mean physical dose for the background liver (Gy) | 11.1 (3.91–24.96) |
| Mean BED2 for the whole liver (Gy) | 36.8 (9.26–99.91) |
| Mean BED2 for the background liver (Gy) | 22.5 (7.49–58.88) |
BED = biologically effective dose.
The background liver was defined as the whole liver minus the PTV. Each physical dose was transformed to BED2 using the linear linear-quadratic model.
