Patent ID: 7893403

Claim:
A radiation image capturing apparatus, comprising: a radiation generator for generating radiation to be applied to a subject: a solid-state radiation detector for detecting the radiation that has passed through the subject; a sensor substrate including a plurality of pixels arranged in a matrix form, the sensor substrate being adapted to store radiation image information generated by the radiation that has passed through the subject as two-dimensional charge information; a plurality of gate lines connected corresponding to each row of the pixels; a plurality of signal lines connected corresponding to each line of the pixels; a gate line driving circuit for driving the plurality of gate lines successively; a reading circuit for reading the radiation image information through the signal lines from the pixels connected to the gate lines being activated; a plurality of charge detecting circuits connected corresponding to the signal lines in the reading circuit, the charge detecting circuits being adapted to detect the charge information supplied from the corresponding signal line as a voltage signal; a temperature sensor is provided in each of the charge detecting circuits for detecting temperature of the corresponding charge detecting circuit; a control circuit for controlling, based on the temperature of the corresponding charge detecting circuit detected by the temperature sensor in the charge detecting circuit, a signal of the radiation image information that is input to the reading circuit to a signal at a predetermined temperature; and an output circuit for outputting the radiation image information with the controlled signal.
