X-Ray diagnostic generator

In an X-ray diagnostic generator suitable for use with a plurality of externally located X-ray tubes, having a high voltage step-up transformer with a secondary connected to high voltage means for rectification, an improvement comprising:

• a single, oil filled, closed housing having AC input connection means connected to a primary of the high voltage step-up transformer, output high voltage connection means adapted to be switchably connected to the plurality of X-ray tubes to supply high voltage between an anode and a cathode of a selected X-ray tube, and
• first and second high voltage control means responsive to external control via control leads, each of said control means being connected between a rectified output of a corresponding one of the high voltage means for rectification and a corresponding section of said output high voltage connection means, each of said high voltage control means being adapted to regulate the output high voltage, and
• said high voltage step-up transformer being positioned and of sufficient dimensions to provide electrical shielding, said high voltage step-up transformer being positioned between said first and second control means to provide electrical shielding therebetween.
