The aim of this work is to provide a method to retrieve the intrinsic resolution of PET detector blocks based on monolithic crystals. Estimating the intrinsic detector resolution is challenging, this resolution is limited by several factors that cannot easily be isolated and studied experimentally, for this reason many works focused on exploring the resolution limits through Monte Carlo...

Monolithic crystals are considered as an alternative for segmented scintillator arrays in positron emission tomography (PET). Monoliths provide good spatial, timing and energy resolutions as well as intrinsic depth of interaction (DOI) encoding. DOI allows reducing parallax errors (radial astigmatism) at off-center positions within a PET ring. This is especially important for high-resolution...

The TT-PET collaboration is developing a compact Time-of-Flight PET scanner for small animals with a 30ps time resolution and sub-millimeter 3D detection granularity. The sensitive element of the scanner is a fully monolithic silicon pixel detector based on state of the art SiGe BiCMOS technology. Our scanner design will be introduced along with detailed GEANT4 simulations concerning hit...

We present results obtained with the PETsys TOFPET2 ASIC Evaluation Kit.
The TOFPET2 ASIC is a time-of-flight capable 64-channel ASIC and is a promising candidate to build high-performance TOF-PET systems.
For a first characterization, we used two KETEK-PM3325-WB SiPMs each equipped with a 3x3x5 mm³ LYSO scintillation crystal.
For the measurements presented in this work, we changed the...

Power supply of PET detectors is a serious issue for
integrated PET/MRI systems, due to mutual interaction between
power supply electronics and MRI magnetic fields. In this work,
we developed a prototype of a magnetic compatible power supply,
that can be safely placed and used in a MRI magnetic field. The
power supply is a highly compact (5.2x5.2 cm) switching DC-DC
converter iron-core...
