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.

Abstract: A sweep device for a storage luminescent screen, in which x-ray images are latently stored, includes a drum having an interior on which the storage screen is mounted, a stimulating radiation source which generates a scan beam of stimulating radiation to cause the storage screen to luminesce picture element-by-picture element, and a deflecting mirror disposed in the center of the drum and rotatable relative to the drum to direct the scan beam onto the screen. The deflecting mirror is disposed in the middle of a measuring head, and the drum is shifted relative to the deflecting mirror for line scanning. For acquiring the light emitted by the storage luminescent screen, a curved light conductor is attached to the measuring head. The curve light conductor has a first end face disposed at the circumference of the measuring head which completely surrounds the point of incidence of the scan beam on the storage luminescent screen.

Abstract: An apparatus for converting radiation image information carried by a storage layer into a television pulse sequence has a drum with a surface on which the storage layer is disposed, a scanning light beam directed to said surface, the drum and the beam being rotatable relative to one another and axially displaceable for conducting a line scan and a change of line. The light signals thus acquired from said storage layer are supplied on an optical path to a photo-electric transducer. A fast and precise conversion of the radiation image information is achieved with the storage layer on the inside wall of the drum and the scan beam conducted via a deflection mirror disposed in the center of the drum, and with a lightguide for the optical connection between the scan surface of the layer and the transducer.
