Abstract
An X-ray generator has an X-ray tube for generating X rays which are detected by an X-ray detector for feedback control of the X-ray tube. The filament current of the X-ray tube is controlled in accordance with the deviation of the X-ray intensity for compensating for any deviation which occurs due to the X-ray tube deterioration or fluctuation of the air density of the X-ray path.
