Design concept of world's first preclinical PET/MR insert with fully digital silicon photomultiplier technology

The development of a highly integrated and MRI-compatible PET detector remains as one of the main challenges towards a truly simultaneous PET/MR scanner. Here we present the world's first PET/MR scanner design "Hyperion II
^D
" with fully digital silicon photomultiplier technology (dSiPMs). It is based on the HYPERImage Insert "Hyperion I" using analog SiPMs demonstrated by Schulz et a!. in [1] and [2]. The new architecture promises outstanding PET performance and increased MRI compatibility as well as improvements in workflow.
