ABSTRACT:
An X-ray inspection apparatus is provided with main detectors each for detecting the absorption amount of X-ray beams delivered from an X-ray focal point, a reference detector for detecting variations in the size or position of the X-ray focal point, and means for removing errors due to influence of the X-ray focal point variations, based on the detention result of the reference detector.
