Dose distributions in the transverse plane for patient 6. The depicted distributions illustrate that the CTV-based robustly optimized plan (panels b, e, h) is insensitive to uncertainties relative to the planning target volume (PTV)-based conventionally optimized plan (panels a, d, g). Panels c, f, i, dose difference between PTV-based plans and robustly optimized plans. (clinical target volume, dark blue segment; brainstem, orange segment; A, anterior; L, left; P, posterior; R; right).
