Abstract
A read-out system for a luminescent storage screen, in which a latent x-ray image is stored, includes a tubular, mirrored light guide having an opening through which light from the storage screeen, caused by scanning the storage screen line-by-line with a beam of read-out radiation, exits onto a detector. The detector is disposed so that its light-sensitive surface is parallel to the scanned line. The light guide has a slot-shaped passage for the scan beam, with ends closed by plates having mirrored surfaces.
