Application of constant vs. variable relative biological effectiveness in treatment planning of intensity-modulated proton therapy

, 2011
To investigate in a simulation study whether using a variable relative biological effectiveness (RBE) in calculation and optimization of intensity-modulated proton therapy (IMPT) instead of using an RBE of 1.1 would result in significant changes in the ...
