ABSTRACT:
The invention relates to an apparatus and method for processing a radiation image. For a subject area, a radiation image signal corrected for leak charge is obtained by subtracting, from a GateOn signal obtained by turning on a transistor switch of a detecting element of a radiation detector, a GateOff signal obtained by turning off the transistor switch. A threshold value is less than or equal to a pixel saturation value. For an unblocked area where the radiation image signal is greater than the threshold value, the GateOn signal is utilized as the radiation image signal.
