摘要： An x-ray tube having a coated x-ray tube frame inner surface and a coated anode assembly is provided. The x-ray tube includes an x-ray tube frame in which an anode assembly is disposed therein. A cathode assembly is also disposed within the x-ray tube frame that emits an electron beam to strike a target surface of the anode assembly and form x-rays. A plasma-sprayed tungsten oxide coating is formed on an inner surface of the x-ray tube frame and on the anode assembly to dissipate heat created by the electron beam.

摘要： An x-ray tube includes an anode comprising a focal track and a cathode assembly configured to emit an electron beam toward a focal spot on the focal track. The x-ray tube also includes a controller configured to wobble the electron beam among a plurality of focal points in a direction tangent to the focal track. The plurality of focal points includes at least one focal point that is bounded by a pair of boundary focal points. The controller is further configured to delay a wobble of the electron beam away from the at least one focal point for a pre-determined amount of time.
