Correction of Geometrical Effects of a Knife-Edge Slit Camera for Prompt Gamma-Based Range Verification in Proton Therapy
Prompt gamma (PG) based Jigsaw range verification can potentially reduce the safety margins in proton therapy.A knife-edge slit camera has been developed in this context using analytical PG simulations as reference for absolute range verification during patient treatment.Geometrical deviations between measurement and simulation could be observed an
