Radiobiological effectiveness and its role in modelling secondary cancer risk for proton therapy
Purpose/Objective(s):
In proton therapy, a radiobiological effectiveness ratio (RBE) of 1.1 (RBE1.1) is often used. In reality, RBE depends on dose, linear energy transfer (LET), biological end point, and tissue type. Using a value of RBE that may be not accurate may affect dose calculation and hence, outcome.
