Abstract:
A radiation image processing apparatus, comprising:a sensor having plural radiation detecting elements arranged in two dimensions, wherein each of the plural radiation detecting elements is irradiated with radiation, converts the irradiated radiation into an electric image signal, and outputs the electric image signal as an image datum of a single pixel so that the sensor outputs image data corresponding to the plural radiation detecting elements; a defect detecting device to receive first image data from a sensor and to detect an image defect caused by a defective element in the first image data and to produce defect information indicating a position of the defective element; a memory to store the defect information; and a correcting device for receiving second image data outputted from the sensor on a condition that the sensor is irradiated with radiation passing through an object, for correcting the second image data on the basis of the defect information read out from the memory, and for producing third image data.
