Patent ID: 8766204

Claim:
A radiographic image generation system, comprising: a console; and a portable radiographic image detector, comprising: a sensor panel unit in which a plurality of radiation detecting elements are two-dimensionally disposed, the radiation detecting elements respectively generate photographed image data by outputting signal values which are proportionate to amount of radiation entering at a time of radiographic image photographing, a readout circuit which reads out dark read values which are output respectively from the plurality of radiation detecting elements in the sensor panel when radiation is not emitted and reads out the photographed image data from each of the plurality of radiation detecting elements at the time of radiographic image photographing performed by emitting the radiation, a wireless communication unit which transmits the photographed image data of each of the radiation detecting elements to the console, a control unit which controls the sensor panel unit, the readout circuit, and the wireless communication unit, and a battery which is built-in to supply an electricity to the sensor panel unit, the readout circuit, the wireless communication unit, and the control unit; wherein the console comprises a wireless communication unit which receives data transmitted from the portable radiographic image detector and which generates a radiographic image based on the photographed image data and offset correction values, the control unit of the portable radiographic image detector controls the readout circuit to read out the dark read values from the radiation detecting elements, the read out being performed for a plurality of times with respect to each of the radiation detecting elements every time the radiographic image photographing is performed, the control unit calculates the offset correction values respectively for the radiation detecting elements based on an average value of the dark read values which are read out for a plurality of times, the control unit transmits the offset correction values and the photographed image data of each of the radiation detecting elements to the console via the wireless communication unit, and the console generates the radiographic image based on the photographed image data and the offset correction values which are transmitted from the portable radiographic image detector via the wireless communication unit.
