ABSTRACT:
An X-ray diagnostic apparatus has a device for controlling an X-ray source with regard to the emission of an X-ray beam and a filter positioner for the introduction or removal of at least one radiation filter into or out of the beam of radiation. A monitoring device checks whether there exists a positive difference signal between an output of a dosage power regulator and a kV controller. Given the presence of a positive difference, the monitoring device controls the filter positioner with regard to the removal of the radiation filter from the beam of radiation.
