ABSTRACT:
An x-ray diagnostics installation has an x-ray source connected to a parameter setting unit which sets exposure parameters (operating characteristics) of the x-ray source, and an x-ray image intensifier video chain. The x-ray image intensifier video chain includes a processing circuit connected to a video pick-up stage and a motion detector. The processing unit controls the parameters of a filter unit for chronological filtering of the video signal. The motion detector is connected to the parameter setting unit for the x-ray source, and controls the filter unit depending on the exposure parameters which are set for a given exposure, such as the level of the video signal, the tube voltage, the radiation dose, and the imaging format of the x-ray image intensifier, all of which are set at the parameter setting unit and which characterize the exposure.
