Fractionation effects in particle radiotherapy: implications for hypo-fractionation regimes.
The aim is to demonstrate the potential impact of changes in the value of the β parameter in the linear quadratic (LQ) model on the calculation of clinical relative biological effectiveness (RBE) values used for high linear energy transfer (LET) radiotherapy. The parameter RBE(min) is introduced into the LQ formulation to account for possible changes in the β radiosensitivity coefficient with changing LET. The model is used to fit fractionated data under two conditions, where RBE(min) = 1 and...Expand abstract
