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).
