摘要: A PET scanner includes a coincidence detector circuit which compares time markers produced by ring of modules. Detector module outputs are sampled every 250 nanoseconds and assembled into event data packets multiplexed through the circuit. The is formed around set ASICs perform comparisons necessary to detect events. Coincidence sorted sinograms used reconstruct images.
