Document Type and Number:
Japanese Patent JPH05502330
Kind Code:
A
Abstract:
An X-ray tube for greatly enhancing the output of photons relative to a standard tube includes a source of an electron beam focused on a target at an angle of approximately 10 DEG to produce high energy photons emitted at an angle along their centerline of 5 DEG to 15 DEG , both angles referring to the surface of the target. Reduction of impurgement of scattered electrons on the tube window is affected in various ways such as use of a magnet to deflect electrons from the photon stream or locating the window out of alignment with the most intense scattered electrons. Scattered electrons are also absorbed by an essentially zero albedo shield disposed in the path of the majority of the scattered electrons not directed at the window.
