An independent monitoring system aiming for the detection of deviations from the prescribed treatment in hadrontherapy is presented. The system is based on prompt gammaray detection via scintillation detectors and the use of time-offlight information. Test measurements at cyclotrons show the influence of degraders used in passive beam delivery...

For the purpose of detecting deviations from the prescribed treatment during particle therapy, the integrals of uncollimated prompt gamma-ray timing distributions are investigated. The intention is to provide information, with a simple and cost-effective setup, independent from monitoring devices of the beamline. Measurements have been...

Prompt secondary radiations such as gamma rays and protons can be used for ion-range monitoring during ion therapy either on an energy-slice basis or on a pencil-beam basis. We present a review of the ongoing activities in terms of detector developments, imaging, experimental and theoretical physics issues concerning the correlation between the...
