- 摘要：
PROBLEM TO BE SOLVED: To provide a defective pixel determination method appropriately determining whether a radiation detection element of a radiation image detector is a defective pixel or not and registering it.
SOLUTION: The defective pixel determination method in a radiation image detector 1 generates live-action image data F(x, y) by converting radiation into an electric signal by a plurality of radiation detection elements (x, y) disposed two dimensionally, corrects characteristic dispersion for every pixel and generates final image data F
0 (x, y). This defective pixel determination method determines, on temporal statistic values &sigmad(x, y) for a plurality of times of dark read values dm (x, y) which are acquired by the dark reading implemented a plurality of times in calibration and outputted from one radiation detection element (x, y), whether the one radiation detection element (x, y) is a defective pixel (xs, ys) or not based on a preset threshold &sigmadth.COPYRIGHT: (C)2010,JPO&INPIT
