Fig. 2

Constant relative biological effectiveness weighted dose distributions of the dose-only optimized reference plans in representative computed tomography slices. Isodoses are displayed relative to the prescription dose to the primary (high-dose) clinical target volume. Arrows depict coplanar (white) and non-coplanar beams (orange) as well as beams passing through the skullcap (green), respectively. Contours show the primary (high-dose) planning target volume (PTV, blue), secondary PTV (black), brainstem (white) and both optic nerves and chiasm (all magenta)
