Table 2.

Doses measured with the in vivo dosimetry and calculated by the TPS Monaco on the chin on top and underneath the bolus for the 11 patients treated at the MRL. *Data of patient #9 were excluded because the measured value was more than 1.5 fold lower from the quartile Q(25)–Q(75) and median of the entire cohort (probably because film was not correctly placed). IQA = interquartile range.
