Figure 2From: Dose-painting intensity-modulated proton therapy for intermediate- and high-risk meningioma Dose distributions in the axial plane of the intensity-modulated proton-beam therapy (IMPT) and photon intensity-modulated radiation therapy (IMRT) plans for the same patient. The union planning target volume (PTVunion) minus the PET-based PTV is in light green (IMPT) and in blue (IMRT).Back to article page
