Table 3 Mean lesion BEDs and deviations from the reference model fmono. Additionally, the percentage of lesions with less than |10| % deviation and only positive deviation from the reference are reported. The latter evaluates how many lesions are overestimated. The mean BED1237,mono (min, max) of the reference model is 8.2 ± 5.0 Gy (2.0 Gy, 21.7 Gy)
