    摘要： Disclosed are a system and method counting photons. Photons are counted through a plurality of counters. Each of the counters generates a flag signal indicating the availability of each counter for an output of a photon detector. The generated flag signal is input into a control unit which controls a switching unit. The control unit allows a signal to be input into a counter, which is not in dead time, based on the received flag signal.
