Depth–dose distributions for 155-MeV proton beams with a 6-cm SOBP width for the cases of RBE-weighted absorbed doses of 0.5, 1, 2, 5 or 10 Gy (RBE), designed to be a constant RBE-weighted absorbed dose in the SOBP region. The solid and dashed lines represent the absorbed dose and RBE-weighted absorbed dose, respectively.
