An AEC device acquires cumulative dose from a start time of the start of irradiation of X-rays until acquisition time after a predetermined time according to the dose signal. According to the cumulative dose, a predicted time point of a reach of the cumulative dose to a target dose is estimated. A stop signal is transmitted to a radiation source controller at the predicted time point, to stop the irradiation of X-rays. | 03-19-2015 |
