A scanning dynamic collimator for spot-scanning proton minibeam production [PDF]
Scientific Reports, 2021 In proton minibeam radiation therapy, proton minibeams are typically produced by modulating a uniform field using a multislit collimator. Multislit collimators produce minibeams of fixed length and width, and a new collimator has to be manufactured each ...
