Abstract: Synchronizing operation between a digital radiographic detector's integration periods and an x-ray generator's x-ray pulse rate by transmitting a frame rate to the detector and the generator. In a first mode, the detector monitors one or more pixels to detect an x-ray pulse. The firing time of the detected x-ray pulse relative to an internal clock of the detector is used to synchronize the detector's integration periods with the pulse rate of the x-ray generator based on the transmitted frame rate and the detected firing time of the x-ray pulses. Successive pulses may also be used to determine a frame rate without prior transmission thereof.
