Abstract

This invention relates to high power X-ray sources, in particular to those equipped with a rotating X-ray anode capable of delivering a higher short time peak power than conventional rotating x-ray anodes. This invention can overcome the thermal limitation of peak power by allowing fast rotation of the anode and by introducing a lightweight material with high thermal conductivity in the region adjacent to the focal track material. The fast rotation can be provided by using sections of the rotating anode disk made of anisotropic high specific strength materials with high thermal stability that can be specifically adapted to the high stresses of anode operation. Uses include high speed image acquisition for X-ray imaging, for example, of moving objects in real-time such as in medical radiography.
