DEFECT INSPECTION UNIT, RADIATION DETECTOR, AND DEFECT INSPECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a defect inspection unit, a radiation detector and a defect inspection method capable of detecting a defect pixel due to break of a wiring.SOLUTION: An X-ray detector 1 has a defect inspection unit 100 which acquires plural dark images corresponding to different detection times (imaging time) in a state that X-ray is not irradiated, and calculates differences among pixel images in plural dark images. As for an area where the calculated difference in pixel images is smaller than a predetermined value, the defect inspection unit 100 determines that a defect pixel due to a wiring break is included, and transmits a piece of information relevant to the position of the defect pixel to a storage 44a.SELECTED DRAWING: Figure 2
