Document Type and Number:
Japanese Patent JP2023159709
Kind Code:
A
Abstract:
To accurately perform irradiation stop control.SOLUTION: A radiographic imaging system comprises a detection unit that detects radiation emitted and incident from a radiation generation device, a calculation unit that calculates a dose of the radiation detected by the detection unit, and a control unit that outputs an irradiation stop signal for stopping irradiation to the radiation generation device when the dose becomes equal to or higher than a threshold. The control unit performs control of changing the threshold depending on an elapsed time from the start of irradiation and sets a change in the threshold on the basis of a reference value for the dose and a delay time obtained using a processing time required for processing from the start of irradiation to the outputting of the irradiation stop signal from the control unit and a time from the output of the irradiation stop signal to the stop of the irradiation at the radiation generation device.SELECTED DRAWING: Figure 1
