Abstract

For x-ray tubes the focal spot temperature is a critical factor. According to an exemplary embodiment of the present invention, an examination apparatus is provided which has a synchronisation unit providing an operation mode for a stereo tube leaving two anodes in which the anode rotation frequency is synchronised with the switching frequency between the anodes such that the switching frequency is a half integer multiple of the anode rotation frequency. This may lead to a significant reduction of the focal spot temperature.
