The x-ray tube, HV generator and HV transformer are enclosed in a common housing. The HV transformer is positioned between the x-ray tube and a collimation tube and has a central channel for passage of the x-ray beam. The HV transformer has an annular winding with an inside wall defining an opening through which the channel for passage of the x-ray beam extends. The channel is pref. defined by a central bore in the HV transformer core contained within the opening defined by the annular winding.
