Abstract
In one example embodiment, an x-ray transmissive window includes an inner surface and an outer surface. An x-ray beam emitted by the x-ray system defines a beam path area on the inner surface of the window and a beam path area on the outer surface of the window. The inner surface is arranged for contact with cooling fluid of the x-ray system and is configured to prevent bubbles present in the cooling fluid from accumulating on the inner surface in the beam path area of the inner surface. The outer surface is configured to prevent fluid droplets from accumulating on the outer surface in the beam path area of the outer surface.
Claims20
An x-ray transmissive window, comprising:
- an inner surface arranged for contact with an x-ray system cooling fluid and configured to substantially prevent bubbles present in the x-ray system cooling fluid from accumulating on the inner surface in a beam path area of the inner surface;
- and
- an outer surface disposed opposite the inner surface and configured to substantially prevent fluid droplets from accumulating on the outer surface in a beam path area of the outer surface.
An x-ray device, comprising:
- a vacuum enclosure within which is disposed an electron-producing cathode and an anode positioned to receive electrons produced by the cathode;
- an outer housing within which is disposed the vacuum enclosure and a cooling fluid;
- and
- an x-ray transmissive window positioned in the outer housing, the x-ray transmissive window including an outer surface and an inner surface, the inner surface arranged for contact with the cooling fluid, wherein the outer surface and the inner surface are non-parallel with respect to level.
An x-ray device, comprising:
- a vacuum enclosure within which is disposed an electron-producing cathode and an anode positioned to receive electrons produced by the cathode;
- an outer housing within which is disposed the vacuum enclosure and a cooling fluid;
- an x-ray transmissive window positioned in the outer housing;
- means for preventing the accumulation of bubbles formed in the cooling fluid on an inner surface of the x-ray transmissive window;
- and
- means for preventing the accumulation of fluid droplets on an outer surface of the housing x-ray transmissive window.
