Abstract: The present invention relates to X-ray generating technology in general. Providing an electron collecting element of an X-ray generating device statically may allow for the manufacture of X-ray systems with reduced moving parts and actuating parts, possibly reducing manufacturing costs and sources for failure. Consequently, an electron collecting element with increased thermal loadability is presented. According to the present invention, an electron collecting element (28) is provided, comprising a surface element (22) and a heat conducting element (26). The heat conducting element (26) comprises a first thermal conductivity in a first direction and at least a second thermal conductivity in at least a second direction. The first thermal conductivity is greater than the second thermal conductivity. The first direction is substantially perpendicular to the surface element (22).

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.
