Abstract
In an exemplary embodiment, a housing of shielding material, surrounding the cathode coils, has an opening for the transmission of the stream of electrons to the anode. A device for effecting a relative movement between the housing and the cathode coils is present, by means of which one of the cathode coils is selectively capable of being covered. The cathode coils can be mounted on a holder which is pivotal about the x-ray tube longitudinal axis by means of electromagnets. The electromagnets can be connected to the output of the filament supply transformer, associated with the respective cathode coil, and a multiplex circuit can be provided for the transmission of the control signals.
