Abstract
An imager includes a flat panel configured to collect charges when the imager operates in a full-power charge integration mode. The imager switches to a low-power standby mode immediately after each image acquisition in the full-power charge integration mode. Bias current flowing through the flat panel is monitored in the standby mode. The imager switches to the full-power charge integration mode when detecting a change in the bias current indicating onset of an X-ray exposure.
