Abstract
A positron emission tomography (PET) system includes a PET detector configured to generate energy signals indicative of a set of events at the PET detector, a first discriminator coupled to the PET detector and configured to generate a primary timing signal in response to a primary event of the set of events, a second, derivative-based discriminator coupled to the PET detector and configured to generate a pileup timing signal in response to a piled-up event of the set of events, and a logic circuit to gate the primary and pileup timing signals of the first and second discriminators.
