FRoG: An independent dose and LET_d prediction tool for proton therapy at ProBeam® facilities

Abstract

We demonstrate that auxiliary dose calculation systems like FRoG can yield excellent agreement to measurements comparable to clinical beam models. Through this work, application of FRoG as a secondary engine at third party cyclotron-based particle treatment facilities is now established for dose verification as well as providing further insight on LET_d and variable RBE distributions for protons, currently absent from the standard clinical TPS.
