M1 - DKFZ-2017-05115 SP - 888 - 905 PY - 2016 AB - Helium ion beams are expected to be available again in the near future for clinical use. A suitable formalism to obtain relative biological effectiveness (RBE) values for treatment planning (TP) studies is needed. In this work we developed a data-driven RBE parameterization based on published in vitro experimental values. The RBE parameterization has been developed within the framework of the linear-quadratic (LQ) model as a function of the helium linear energy transfer (LET), dose and the tissue specific parameter (α/β)ph of the LQ model for the reference radiation. Analytic expressions are provided, derived from the collected database, describing the RBEα = αHe/αph and Rβ = βHe/βph ratios as a function of LET. Calculated RBE values at 2 Gy photon dose and at 10 KW - Radioisotopes (NLM Chemicals) KW - Helium (NLM Chemicals) LB - PUB:(DE-HGF)16 C6 - pmid:26740518 DO - DOI:10.1088/0031-9155/61/2/888 UR - https://inrepo02.dkfz.de/record/129110 ER -
