Abstract
An X-ray tube assembly includes an anode, a cathode, and an X-ray transparent window. The anode includes an X-ray-producing target having a surface. The cathode has an electron-beam axis which intersects the target surface at a focal point and which is oriented at a first angle, with respect to the target surface, wherein the first angle is generally twenty degrees. The window includes a surface having a center point. A line between the focal and center points makes a second angle, with respect to the target surface, wherein the second angle is generally seven degrees. A method for producing X-rays employs these angles.
