Abstract
A read system for a luminescent image storage screen in an x-ray diagnostics installation, the luminescent screen latently storing an x-radiation image, includes a source of readout radiation which excites the storage screen to luminesce, a photo-multiplier detector which receives light emitted by the storage luminescent screen and converts the incident light into electrical signals in the form of a pulse sequence having a pulse rate dependent on the brightness incident on the light-sensitive entry face of the photo-multiplier, and a counter which counts the pulses at the output of the detector. The output of the counter is supplied to a monitor through a converter for generating a visual image.
