ABSTRACT:
In an exemplary embodiment in order to establish the desired relationship between x-ray tube voltage and x-ray tube current, at least one series resistance is connected in the power path between the mains and the x-ray tube. A switching device for by-passing the series resistance is present which is controlled by a comparator for the actual value and setpoint value of the x-ray tube voltage in such a fashion that the series resistance is by-passed at the commencement of a radiograph as long as the actual value is smaller than the setpoint value.
