FRoG-assisted treatment design is displayed with five potential plans (Tx.#1-.#5). Beam angle arrangement for the various plans using 2 or 3 beams, clinical RBE (RBE1.1), variable RBE applying the McNamara et al. model (vRBEMCN) and LETd (b). RBE-weighted dose volume histogram (DRBEVH) applying vRBEMCN and LETd volume histogram (LETVH) in the contralateral optic nerve (L) for the five plans (I-V) are displayed (c)
