摘要

PROBLEM TO BE SOLVED: To provide an abnormal pixel determination method capable of accurately determining whether or not the radiation detection element of a radiograph detector is an abnormal pixel or a defective pixel.;SOLUTION: In the abnormal pixel determination method in the radiograph detector 1 having the plurality of radiation detection elements (x, y) for outputting actual image data F(x, y) in radiography and outputting a dark read value D(x, y) in dark read, on the basis of the actual image data F(x, y) outputted in the radiography or the dark read value D(x, y) outputted in the dark read performed at least once before or after the radiography from one radiation detection element (x, y) and the actual image data F(x', y') or the dark read value D(x', y') outputted from the plurality of radiation detection elements made to correspond to the radiation detection element (x, y) beforehand, whether or not the one radiation detection element (x, y) is the abnormal pixel is determined.;COPYRIGHT: (C)2010,JPO&INPIT
