Abstract

See full text

An X-ray system includes an X-ray source directing X-radiation on a first path through a subject to an X-radiation receptor which responds to X-rays to direct light radiation on a secondary path to a light image plane. In either path or both paths is a rotating radiation-opaque mask having one or more spiral radio-transparent windows which sweep through the path as the mask rotates. Each spiral window may be formed by the overlap of coaxial spiral windows in superimposed masks which are relatively adjustable in phase to vary the window width.
