Results of the simulation of total treatment dose for EBRT + 4 fractions of HDR BT. The mean of the total simulated dose in EQD2 is shown for typical expected dose levels for OAR and HR CTV, assuming typical values for random uncertainties as observed in our analysis. Expected total doses (without taking into account dosimetric uncertainties) are indicated by vertical dotted lines. Total EQD2 (with α/β = 3 Gy for OAR and α/β = 10 Gy for HR CTV) are plotted against the simulated random uncertainty (SD) of the whole treatment dose, in Gy EQD.
