摘要： An X-ray assembly may include a vacuum wall, an anode, and a cathode. The vacuum wall may define a vacuum enclosure and may include an X-ray window. The anode may be located within the vacuum enclosure. The anode may include a target area. The cathode may be located within the vacuum enclosure. The cathode may generate an electron stream to travel to a focus area located at the target area of the anode. The cathode may be positioned such that the electron stream travels along an oblique path relative a virtual line positioned so as to intersect a center of the focus area and a center of the X-ray window.
