Radiographic image capture device, system, program storage medium and method

A radiographic image capture system comprising:

• a radiographic image capture device comprising a radiation detector including a plurality of detection pixels that detect a radiation application state and a plurality of imaging pixels that capture a radiographic image, and an application section that applies a bias voltage to each of the plurality of detection pixels and to each of the plurality of imaging pixels;
• and
• a controller that effects control such that, if the radiation application amount detected by the plurality of detection pixels is equal to or greater than a first threshold value during a first state in which the bias voltage is applied to the detection pixels, the application section is caused to transition to a second state in which the bias voltage applied to the detection pixels is reduced.

A non-transitory computer readable program storage medium that stores a program that causes a radiographic image capture device to perform a processing, the radiographic image capture device including a radiation detector including a plurality of detection pixels that detect a radiation application state and a plurality of imaging pixels that capture a radiographic image, and an application section that applies a bias voltage to each of the plurality of detection pixels and to each of the plurality of imaging pixels, the processing comprising:

• determining whether or not the radiation application amount detected by the detection pixels during a first state in which the bias voltage is applied to the detection pixels is equal to or greater than a first threshold value;
• and
• controlling the application section to transition to a second state in which the bias voltage applied to the detection pixels is reduced if it is determined that the application amount is equal to or greater than the first threshold.

A radiographic image capture method for a radiation detector including a plurality of detection pixels that detect a radiation application state and a plurality of imaging pixels that capture a radiographic image, the method comprising:

• determining whether or not a radiation application amount detected by the plurality of detection pixels during a first state, in which a bias voltage is applied to the plurality of detection pixels, is equal to or greater than a first threshold value;
• and
• transitioning to a second state in which the bias voltage applied to the plurality of detection pixels is reduced if it is determined that the application amount is equal to or greater than the first threshold value.
