Abstract
An x-ray diagnostics installation has an operating voltage generator, an x-ray tube, an x-ray image intensifier, a video camera, a video amplifier having controllable gain, an integration circuit and a control circuit that acts on the operating voltage for dose rate control. The x-ray diagnostics installation is fashioned such that the control circuit is connected to the video amplifier and to the integration circuit and controls these components such that the gain of the video amplifier is raised when a limit value of the dose rate control is reached, with parameters of the integration circuit being simultaneously modified.
