Abstract
An X-ray tube assembly including a cathode having an electron emitting surface, a rotatable anode having an X-ray target surface, and a vacuum-enclosing rotatable frame surrounding, and spaced apart from, the electron emitting surface and the X-ray target surface. The frame is hermetically attached to the anode, and the frame includes a totally-annular and X-ray-transparent window ring. Load-carrying bearings are located outside the vacuum of the frame and rotatably support the frame and the anode.
