A Monte Carlo positronium decay source model with multiple annihilation channels in GATE
Wojciech Krzemien, Mateusz Bala, Kamil Dulski +10
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…
