Table 1: Average differences between photon plans and non-gated proton plans mean and maximum doses of relevant OARs.

The differences between proton plans simulated with and without gating were not significant on average, and the gated modality was beneficial only for a selection of patients. Figure 1 shows a representative case where the gated modality could be preferred.
