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. The curve light conductor has a second end face disposed substantially in the middle of the measuring head perpendicular to the drum axis, and opposite the light-sensitive surface of an emitted radiation detector. The detector converts the emitted radiation into an electrical signal sequence.
