OSTI ID:6960001
The patent describes an X-ray system for radiological examination of a subject. It comprises: an X-ray source directing radiation on a path through a subject position; an X-ray scintillation screen on the path beyond the subject position responsive to X- radiation to produce a secondary, planar light image; optical means projecting the secondary image from the scintillation screen on a light path; and a light image intensifier tube beyond the optical means for amplifying the intensity of the light image. Wherein the intensifier tube has a planar input face receiving a planar projected light image, and the system includes a movable light mask between the scintillation screen and intensifier tube with an image scanning aperture substantially at the plane of the projected light image.
