Graph Attention Network for Multi-Isotope PET Random Event Correction
LinkFramed PET random coincidence correction as binary edge classification on detector hit graphs. Designed a 3-stage GNN (linear encoder → 2-layer GATv2 → MLP classifier) trained on 3.25M labeled graphs from GATE Monte Carlo simulations. Achieved 92.9% precision, 92% recall, F0.5 = 0.927 on test set.
