Abstract
In an X-ray system in which a source directs X-radiation through a subject to a receptor which produces a secondary planar light image, the light image is projected on the planar input face of a light intensifier after passing through the scanning aperture of a moving mask substantially at the plane of the projected light image. Preferably the system includes a moving X-ray mask with a scanning aperture between the source and receptor and means driving the X-ray and light masks in synchronism with their apertures optically superimposed.
