ABSTRACT:
An X-ray image processing apparatus includes an arithmetic operation section for processing the X-ray image data, to eliminate X-ray scattered components (first blurring factor) and a veiling glare (second blurring factor) which occurs when an image intensifier converts X-ray image to a photo-image, and a TV camera converts the photo-image to an image signal. The X-ray image data obtained by eliminating the scattered components and the blurring components derived from the veiling glare includes only blurring components (third blurring factor) derived from the characteristics of an X-ray tube, an image intensifier, and TV camera. A blurring restoration filter circuit is provided, for forming a filter for restoring the blurring from the third factor.
