Study of a novel inverted collimator concept for prompt-gamma-based range verification in proton therapy using a hybrid simulation approach
Objective. Prompt-gamma imaging is a promising technique for in-situ range verification during proton therapy, with the potential to reduce range uncertainties. Current prompt-gamma cameras typically rely on mechanical collimators, among which the knife-edge slit (KES) and multi-parallel slit (MPS) collimators are the...
