Abstract
The present invention provides an X-ray image detector ( ) which can reduce the size of a whole apparatus associated with an X-ray imaging tube, reduce noise components of an output X-ray image even if an incident X-ray is very weak, and provide a distortion-free visible image or electric image. The X-ray image detector ( ) comprises a vacuum container having an input fluorescent screen outputting fluorescent light, a photoelectric screen converting the fluorescent light which is output from the input fluorescent screen to a photoelectron, and an output fluorescent screen outputting a visible light image with the obtained electron, a plurality of image pick-up elements ( ) arranged such that partially overlapped areas are outside an image taking area and taking the visible light image in a divided way, image processing circuits ( ) so arranged as to correspond to the image pick-up elements and trimming a taken video signal, an output image processing circuit ( ) obtaining a composed image and a display device ( ) displaying it as one signal.
