摘要
A rotating-anode X-ray tube for producing a flat wide-angle fan-shaped beam with a substantially uniform distribution of energy comprises a cylindrical anode and a cathode axially or peripherally offset from the target area or focus bombarded by the electrons so that the axis of the fan-shaped beam emitted by that area can extend radially to the cylindrical anode surface. An arcuate shield closely paralleling this cylindrical surface is apertured at its center in front of the focus and intercepts stray electrons which would be liable to bombard the anode at points outside the target area so as to give rise to extra-focal radiation. Such a tube is useful in apparatus designed for axial transverse tomography.
