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