In PET systems with a geometry different from a closed ring, the Time of Flight (TOF) of the annihilation photons appears to be relevant. Such a system capability helps to compensate the missing angular information that generates artifacts on the reconstructed images. In this work, two ASIC designs are evaluated for their use in PET systems having accurate coincidence resolving times (CRT) while preserving...
A whole-body PET device is sometimes not suitable for brain studies because the achieved image resolution is typically not sufficient to investigate small size structures. Thus, a dedicated brain PET insert system with high performance would overcome such limitations. Moreover, these functional studies lack of anatomical information. It is shown elsewhere the convenience of simultaneously acquisition...
This works shows the feasibility study performed with a new small animal PET design based on SiPM arrays in front of a high field MR scanner. The PET ring is made out of 8 detector blocks each containing a single monolithic 50×50×10 mm3 LYSO block and coupled to an array of 12×12 SiPMs. The PET system performance has been evaluated both alone and in front of the MR with about 400–500 mT magnetic field...
Gamma ray detectors merging continuous and pixelated crystal arrays are described. We show a pilot study about the detector performance of an innovative scintillation design that simultaneously uses both a continuous and a crystal array. This novel idea is the base of a high-resolution and high-sensitivity gamma ray detector. Alternatively monolithic or crystal arrays can be mounted on the front or...
Monolithic scintillation crystals offer the possibility to preserve the scintillation light distribution, specially when black painted. Furthermore, the statistical moments of that distribution can provide accurate information about the three spatial components.
