We report on the progress a first generation of realistic size metascintillators for time-of-flight PET. These heterostructures combine dense LYSO or BGO plates, interleaved with fast scintillator layers producing bunch prompt photons from energy leakage recoil photoelectric electron. From Geant4 simulation sharing distribution between and 42 LYSO-based BGO-based configurations, detailed study ...

UNLABELLED Significant improvements have made it possible to add the technology of time-of-flight (TOF) to improve PET, particularly for oncology applications. The goals of this work were to investigate the benefits of TOF in experimental phantoms and to determine how these benefits translate into improved performance for patient imaging. METHODS In this study we used a fully 3-dimensional sc...

The main thrust for this work is the investigation and design of a whole-body PET scanner based on new lanthanum bromide scintillators. We use Monte Carlo simulations to generate data for a 3D PET scanner based on LaBr3 detectors, and to assess the count-rate capability and the reconstructed image quality of phantoms with hot and cold spheres using contrast and noise parameters. Previously we h...

Due to its effectiveness in monitoring highly tumourconformed charged hadron therapy, in-beam positron emission tomography (in-beam PET [1]) is strongly desirable at charged hadron facilities under construction [2] or planning [3]. We present, therefore, optimized arrangements of the γ-ray detectors for next-generation in-beam PET scanners. A versatile, fully 3D, maximum likelihood expectation ...
