Fig. 2

Representative transversal images show the IMRT plan (A) and the proton plan (B) of a patient with glioblastoma of the right temporal lobe. The DVH shows some of the relevant organs at risk in corresponding colors in solid and dashed lines, for IMRT and proton beam radiotherapy, respectively. While the PTV (red) coverage is similar in both techniques, dose to the surrounding organs is reduced in the proton plan
