Abstract
An x-ray diagnostics installation has a solid-state image transducer with a layer whose electrical resistance is dependent on the intensity of incident radiation from an x-ray source, and an electro-luminescent layer in contact therewith which converts the resistance into a corresponding brightness value. Due to the decay time of the electro-luminescent layer, an image will be temporarily stored in the solid-state image transducer after the x-ray source has been deactivated. This temporarily stored image is read-out, after deactivation of the x-ray source, by a scanner for converting the brightness of the picture elements of the electro-luminescent layer into corresponding electrical signals. These signals are supplied to a data acquisition and processing system, which generates an image for display.
