Abstract
An x-ray tube assembly (16) includes a housing (40) and an insert frame (52) supported within the housing (40), such that the insert frame (52) defines a substantially evacuated envelope in which cathode (56) and anode (54) assemblies operate to produce x-rays. An x-ray transmissive window assembly (70) extends between and in a fluid-tight relationship with the housing (40) and the insert frame (52). The window assembly (70) includes an insert window (72) brazed to the insert frame (52), a top plate (76), which is connected to and substantially surrounded by a flange (78), where the flange (78) is fastened to the x-ray tube housing (40). An annular side plate (86) is connected to a fluid-tight relationship with both the insert frame/window interface (74) and the flange (78). The window assembly (70) cools the window through enhanced heat transfer while preventing housing coolant from contacting the insert window (72), thereby eliminating coolant carbonization on the window (72) and enhancing x-ray beam quality.
