Temporal imaging: Observation and localization of a compton effect inside a 20 mm monolithic LYSO plate with a Philips digital Si-PM

Abstract : Recently, temporal imaging has been shown to be very promising for enhancing the accuracy of spatio-temporal localization of a scintillation events within a monolithic scintillator [1]. The objective of this communication is to show that, besides scintillation localization performances, Compton events could be efficiently detected and characterized inside a monolithic plate. A time-based robust Compton event reconstruction could lead to the implementation of a cost effective single plate Compton camera based on monolithic scintillating crystals.
