X-ray tube aperture body with shielded vacuum wall. In one example embodiment, an aperture body for use in an x-ray tube having an anode and a cathode includes an electron shield and a vacuum wall. The electron shield is configured to intercept backscattered electrons from the anode. The vacuum wall is separated by a gap from the electron shield and is shielded from the backscattered electrons by the electron shield. The aperture body also includes an electron shield aperture defined in the electron shield and a vacuum wall aperture defined in the vacuum wall through which electrons may pass between the cathode and the anode.
