abstract = {The potential of proton therapy is currently limited due to
large safety margins. We estimated the potentialreduction of
clinical margins when using prompt gamma imaging (PGI) for
online treatment verification ofprostate cancer. For two
adaptive scenarios a potential reduction relative to
clinical practice was evaluated. Theuse of a trolley-mounted
PGI system for online treatment verification to trigger an
adaptation reduced the currentrange margins from 7 mm to 3
mm. In a case example, the dose reduction due to reduced
range margins wassubstantially larger compared to reduced
setup margins when using pre-treatment volumetric imaging.},
