Simulation Study of a 3-D Multislit Prompt Gamma Imaging System for Proton Therapy Monitoring

The Bragg peak phenomenon empowers proton therapy in targeted dose delivery in principle and also critically demands high accuracy of proton beam’s dispatch track in practice. To ensure the accuracy, prompt gamma imaging (PGI) systems were studied for monitoring the delivery of proton beams in real time. In this work, a dual-head PGI system was proposed and optimized with multislit collimators and...
