摘要： Examples of the present disclosure relate to a particle beam dose profile measurement apparatus comprising a particle detector stack comprising a plurality of scintillator layers. Each scintillator layer of the detector stack is disposed along an axis of the apparatus such that the axis projects through each layer. Each scintillator layer is configured to produce scintillation light indicative of an energy deposition, in that scintillator, of a particle beam incident upon the detector stack along said axis. The apparatus comprises readout circuitry configured to measure the scintillation light of each scintillator layer; and dose profile determination circuitry configured to determine a dose profile of said particle beam within the detector stack. Said determining is based on the measured scintillation light of each scintillator layer, and a quenching correction.
