Abstract:
An x-ray tube assembly including:an x-ray tube housing; a cathode assembly; a rotating anode assembly; an insert frame supported within the x-ray tube housing, said insert frame defining a substantially evacuated envelope in which the cathode and anode assemblies operate to produce x-rays; an x-ray transmissive window assembly which extends between and in a fluid-tight relationship with the x-ray tube housing and the insert frame, the x-ray transmissive window assembly including: an x-ray transmissive insert window hermetically connected to the insert frame; an x-ray transmissive top plate connected to and substantially surrounded by a flange, said flange being fastened to the x-ray tube housing; and, an annular side plate having first and second ends, the first end being hermetically connected to at least one of the insert frame and insert window, and the second end is connected to a bottom surface of the flange; and, a dielectric liquid coolant which flows between the x-ray tube housing and the insert frame and around the annular side plate for indirectly cooling the x-ray transmissive window.
