[EN] In this work we present a method to efficiently collect scintillation light when using monolithic
scintillator crystals. The acceptance angle of the scintillation light has been reduced by means of optical
devices reducing the border effect which typically affects continuous crystals. We have applied this
procedure on gamma detectors for PET systems using both position sensitive PMTs and arrays of SiPMs.
In the case of using SiPMs, this approach also helps to reduce the photosensor active area.
We evaluated the method using PMTs with a variety of different crystals with thicknesses ranging
from 10 to 24 mm. We found that our design allows the use of crystal blocks with a thickness of up to
18 mm without degrading the spatial resolution caused by edge effects and without a significant
detriment to the energy resolution. These results were compared with simulated data. The first results of
monolithic LYSO crystals coupled to an array of 256 SiPMs by means of individual optical light guides are
also presented.
