Three-Photon Bayesian Imaging of Ortho-Positronium
L. Raczynski, W. Krzemien, A. Coussat +5
PET provides functional images relying on two-photon coincidences from positron-electron annihilation. In human tissue, about 40\% of annihilations are preceded by Ps formation, of…
A Monte Carlo positronium decay source model with multiple annihilation channels in GATE
Wojciech Krzemien, Mateusz Bala, Kamil Dulski +7
Positronium-based imaging requires realistic modelling of positronium (Ps) decay in matter. We introduce a modular Ps decay model implemented in GATE 9.4 and GATE 10, enabling the…
Development of the normalization method for the first large field-of-view plastic-based PET Modular scanner
A. Coussat, W. Krzemien, J. Baran +4
In positron emission tomography acquisition (PET), sensitivity along a line of response can vary due to crystal geometrical arrangements in the scanner and/or detector inefficienci…
