Abstract: An x-ray tube unit includes an x-ray tube unit housing, in which a vacuum housing is disposed, which includes a high-voltage component. The vacuum housing includes an insulating medium circulating in the x-ray tube unit housing flowing around it. Further, a cathode module and an anode are disposed in the vacuum housing, the cathode module lying at high voltage and including an emitter which emits electrons when heating current is fed to it. In addition, a potential difference is present between the cathode module and the anode for accelerating the emitted electrons. In accordance with an embodiment of the invention a high-voltage feed, a heating transformer and a radiation protection component are integrated into the high-voltage component, the high-voltage component being filled at least partly with an electrically-insulating encapsulation material. This produces a compact and installation-friendly x-ray tube unit which has high operational safety.

Abstract: The invention relates to a radiation application apparatus for applying radiation at a location within an object. The radiation application apparatus comprises a transforming unit (2) for being arranged within the object at the location and for transforming ultrasound energy to electrical energy, and a radiation source (4) for being arranged within the object and for generating radiation (5) to be applied at the location within the object, wherein the radiation source (4) is driven by the electrical energy. Since the transforming unit transforms the ultrasound energy to electrical energy being used by the radiation source, it is not necessary to transfer electrical energy to the radiation source, i.e., for example, corresponding cables, which may have to be isolated, are not necessarily required. Insulation problems and corresponding safety problems, which may be present, if cables, in particular, corresponding high voltage cables, are used, can therefore be reduced.
