摘要:
A read-out system for a luminescent storage screen of the type used to latently store an x-ray in an x-ray diagnostics apparatus includes a radiation source which generates a scan beam, which is deflected over the storage screen to cause the storage screen to luminesce pixel-by-pixel, with the emitted light being supplied to an image reproductions circuit for generating a visible image. A portion of the scan beam is coupled-out and is conducted to a correction detector unit, which supplies a correction signal containing information regarding the intensity, and further information about the location, of the deflected scan beam. The output signals of the detector and the correction detector are superimposed so that any errors caused by fluctuations in the brightness of the scan beam, or non-uniformities in the structure of the detector, will be corrected.
