Spiking neural networks (SNN) are investigated for detecting photon coincidences in positron emission tomography (PET) data.
PETNet interprets detector hits as a binary-valued spike train and learns to identify photon coincidence pairs.
PETNet outperforms the state-of-the-art classical algorithm with a maximal coincidence detection F1 of 95.2%.
PETNet predicts photon coincidences up to 36 times faster than the classical approach, demonstrating the potential of SNNs in particle physics applications.
