Purpose:
The authors have developed a trimodal PET/SPECT/CT scanner for small animal imaging. The gamma ray subsystems are based on monolithic crystals coupled to multianode photomultiplier tubes (MA-PMTs), while computed ...

In this paper we describe the overall design of a PET–MR system for head imaging within the
framework of the DREAM Project as well as the first detector module tests. The PET system design
consists of 4 rings of 16 ...

[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 ...
