Abstract: A rotating anode for an x-ray tube has an anode body composed of composite fiber material, mounted in a bearing system, the anode body having a target surface with a focal ring and including fibers with particularly high heat conductivity in the longitudinal direction. An axis-proximal cooling system is associated with the anode body. The majority of all fibers with high heat conductivity in the longitudinal direction terminate bluntly both at the focal ring and at the cooling system, such that their abutting faces respectively are in direct, heat-conducting contact both with the focal ring and with the cooling system.

Abstract: A system and method for cooling an X-ray tube in a computer tomography (CT) cooling system is shown having a heat exchanger that has at least one cooling passageway for receiving a coolant for cooling the X-ray tube and that is formed to define a tubular passageway having or defining a heat exchanger axis. The tubular passageway has a first open area and a second open area, and, in one embodiment a first axial fan and a second axial fan, respectively, are situated adjacent to the first and second open areas. The heat exchanger is mounted on a gantry of the computerized tomography system such that the axis of the axial fans and the heat exchanger axis are generally parallel to the gantry axis so as to reduce or minimize the effects of gyroscopic forces.
