Abstract:
An X-ray diagnostic installation comprising:an X-ray tube which emits an X-ray beam; an X-ray image converter on which said X-ray beam is incident, said X-ray image converter generating electrical signals representing a raw image subject to disturbances; an image system supplied with said electrical signals for generating signals representing a visible image therefrom, said image system including a device for offset correction which generates an offset image from said electrical signals, a correction offset memory in which said offset image is stored, and an analysis module preceding said correction offset memory which analyzes said offset image to determine a presence of said disturbances therein and which allows storage of said offset image in said correction offset memory only if said offset image is free of said disturbances, and processing circuitry for generating said signals representing said visible image from said offset image; and a playback device to which said signals representing said visible image are supplied for playback of said visible image.
