: In Positron Emission Tomography (PET), matching pairs of photons (coincidences) is computationally expensive at high rates.
Based on current technical and academic data, here are the most relevant "reviews" and interpretations of coincidence theory in this context: 1. Mathematical Coincidence Theory kitheory_coincidence
If you are looking for a review of the academic field, is a robust branch of mathematics. Purpose : It studies the set of points where two continuous maps : In Positron Emission Tomography (PET), matching pairs
