Abstract: The present invention relates to X-ray tube technology in general. Most of the energy applied to the focal spot via electron bombardment is converted to heat; the generation of electromagnetic radiation may be considered to be quite inefficient. One of the central limitations of X-ray tubes is the cooling, thus the dissipation of heat, of the anode element, in particular the focal track. Consequently, an anode disk element that may sustain increased heat while still maintaining structural integrity and furthermore that may provide improved dissipation of heat from the focal track is presented. According to the present invention, an anode disk element (1), comprising an anisotropic thermal conductivity, for the generation of X-rays is provided. The anode disk element (1) comprises a focal track (4) and at least one heat dissipating element (5). The anode disk element (1) is rotatable about a rotational axis (6) with the focal track (4) being rotationally symmetrical to the rotational axis (6). The at least one heat dissipating element (5) is adapted for heat dissipation from the focal track (4) in the direction of reduced thermal conductivity of the anode disk element (1).

Abstract: The present invention relates to X-ray generating technology in general, in particular, it relates to an anode disk element (1) for an X-ray generating device (21). The generation of electromagnetic radiation may be considered to be quite inefficient, since a substantial part of energy applied to a focal track is converted to heat rather than X-radiation. Thus, a limiting factor in the operation of X-ray tubes is the cooling of the anode element and more specifically the focal track. In the present invention, an anode disk element is provided, with an improved dissipation of heat from the focal track. Thus, the anode disk element may sustain increased heat while maintaining structural integrity. The anode disk element (1) comprises at least a first surface (2) and a second surface (3), with the first surface (2) comprising a focal track (4) and the second surface (3) comprising a conductive coating (5). The anode disk element (1) is rotatable about a rotational axis (6) with the focal track (4) being rotationally symmetrical to the rotational axis (6). The first surface (2) comprising the focal track (4) and the second surface (3) comprising the conductive coating (5) are adjacently arranged.

Abstract: An x-ray device has a cathode aligned on a target region in a tube housing with a rotating anode unit. The rotating anode unit is borne to rotate around a rotational axis inside the tube housing. The rotating anode unit has a rotating anode plate with the target region and a shaft rotationally connected with the rotating anode plate. A magnetic bearing supports the shaft without contact in the tube housing. The rotating anode plate has an axial extension facing away from the shaft. The axial extension dips into a fluid-filled receptacle space of the tube housing for heat dissipation. Such an x-ray device allows high rotation speeds of the rotating anode unit, and thus a high operational power.

Abstract: The invention relates to a method for manufacturing a highly heat-conductive heat sink from carbon material, in particular, a rotatable anode heat sink of an X-ray tube, comprising an anode body rotatable on a rotational axis with a focal ring that runs perpendicularly to the axis and is heat conductively connected to the heat sink. To achieve a higher degree of heat conductivity than that of prior art heat sinks, the invention proposes that for making a heat sink a mixture of carbon nanotubes and a binder is molded and subsequently heat-treated.
