Comparison of dose distribution in three different modalities for a patient with intracranial germ cell tumor: (A) Pencil beam scanning proton beam therapy (PBS-PT) plan. (B) Intensity-modulated radiotherapy (IMRT) plan. (C) Volumetric modulated arc therapy (VMAT) plan. PTV_Low is delineated in orange, PTV_High in red. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
