摘要： A radiation imaging system comprising a radiation imaging apparatus in which pixels are arranged, a radiation source, a display unit, and a controller is provided. The controller causes, during radiation irradiation, the radiation imaging apparatus to repeat a generation operation of generating one image data by causing the pixels to perform an accumulating operation and a readout operation. When it is instructed to terminate the radiation irradiation, the controller causes the radiation source to stop the radiation irradiation in accordance with completion of the accumulating operation and the readout operation of the last row in the generation operation during which it was instructed to terminate the radiation irradiation, and causes the display unit to display an image based on last image data generated by the generation operation during which it was instructed to terminate the radiation irradiation.

摘要： An imaging control unit in a radiation imaging apparatus causes imaging in a plurality of modes varying in a setting value, and causes standby driving to reduce signals stored in a plurality of pixels during a period in which the plurality of pixels is not irradiated with radiation. The plurality of modes includes a first mode for first imaging using a first setting value and a second mode for second imaging using a second setting value different from the first setting value after the first imaging. The imaging control unit causes the standby driving using a setting value closer to the second setting value than to the first setting value in response to end of the first imaging in causing the second imaging.
