Abstract
A lightweight X-ray tube assembly and X-ray CT equipment having the same. The X-ray tube assembly includes an X-ray tube and a tube housing. The X-ray tube includes: a cathode for generating an electron beam; an anode for radiating X rays by collision of the electron beam; an envelope for holding the cathode and the anode in a vacuum atmosphere; and an X-ray window provided in the envelope to irradiate some of X rays radiated from the anode toward a test subject. The tube housing encapsulates the X-ray tube together with an insulating oil. The X-ray tube assembly further includes a protective member that is provided at least around the X-ray window on an outer wall of the envelope and shields the X rays.
