Radiographic imaging control device, radiographic imaging system, radiographic imaging device control method, and recording medium

A radiographic imaging device control method comprising:

• (a) with a resetter of an amplifier, resetting charges remaining at an integration capacitor before imaging, the amplifier being provided in correspondence with a respective pixel of a radiation detector in which a plurality of the pixels are arrayed, each pixel including a sensor portion that generates charges in accordance with irradiated radiation and a switching element that is for reading out the charges generated at the sensor portion, and the amplifier being equipped with the resetter that resets the remaining charges and amplifying an electronic signal according to the charges read out by the switching element from the corresponding pixel by a pre-specified amplification factor;
• and
• (b) in accordance with a pre-specified condition, controlling so as to alter a bias current supplied to the amplifier in at least some periods of resetting by the resetter in (a).

A non-transitory recording medium storing a radiographic imaging control program that causes a computer to execute a process comprising:

• (a) with a resetter of an amplifier, resetting charges remaining at an integration capacitor before imaging, the amplifier being provided in correspondence with a respective pixel of a radiation detector in which a plurality of the pixels are arrayed, each pixel including a sensor portion that generates charges in accordance with irradiated radiation and a switching element that is for reading out the charges generated at the sensor portion, and the amplifier being equipped with the resetter that resets the remaining charges and amplifying an electronic signal according to the charges read out by the switching element from the corresponding pixel by a pre-specified amplification factor;
• and
• (b) in accordance with a pre-specified condition, controlling so as to alter a bias current supplied to the amplifier in at least some periods of resetting by the resetter in (a).
