(54) X-ray tube having a unitary target, stem and rotor hub


(57) An x-ray tube target element in which a target disk portion, a stem portion and a base portion are integral. The elements are composed, alternatively, of metals frequently used for target disks alone or of graphite. A layer of an alloy, such as tungsten-rhenium, disposed circularly on a face of the target disk substrate constitutes the focal track of the target. The base of the element is adapted for coupling it directly to the anode rotor assembly.
