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.

Abstract: The present invention is related to high power X-ray sources, in particular to those ones that are equipped with rotating X-ray anodes capable of delivering a much higher short time peak power than conventional rotating X-ray anodes according to the prior art. The herewith proposed design principle thereby aims at overcoming thermal limitation of peak power by allowing extremely fast rotation of the anode and by introducing a lightweight material with high thermal conductivity (2) in the region adjacent to the focal track material (4). The extremely fast rotation is enabled by providing sections of the rotary anode disk made of anisotropic high specific strength materials with high thermal stability (1, 3, 6) which will be specifically adapted to the high stresses building up when the anode is operated, as for example fiber-reinforced ceramic materials. An X-ray system equipped with a high peak power anode according to the present invention will be capable of high speed image acquisition with high resolution and high coverage. Such a high-speed rotary anode disk can advantageously be applied in X-ray tubes for material inspection or medical radiography, for X-ray imaging applications which are needed for acquiring image data of moving objects in real-time, such as e.g. in the scope of cardiac CT, or for any other X-ray imaging application that requires high-speed image data acquisition. According to a further exemplary embodiment, the invention is directed to a rotary anode disk divided into distinct anode segments (10a, 10b) with adjacent anode segments which may e.g. be limited to each other by straight radial (14a) or S-shaped slits (14b) ranging from the inner anode bulk (1) to the inner radial edge of the anode disk's outer frame section (3). Other exemplary embodiments of the present invention relate to a rotary anode disk structure design which comprises liquid metal conductors (16a) between the inner anode bulk (1) and a rotary shaft (12) needed for rotating the rotary anode disk about its rotational axis (5), said liquid metal conductors (16a) providing a liquid metal connection between the rotary anode and its rotary shaft (12), or to a rotary anode disk structure which comprises a sliding radial connection (17) and a flexible heat conductor (18) between the inner anode bulk (1) and the rotary shaft (12).

Abstract: For x-ray tubes the focal spot temperature is a critical factor. According to an exemplary embodiment of the present invention, an examination apparatus is provided which has a synchronisation unit providing an operation mode for a stereo tube in which the anode rotation frequency is synchronised with the switching frequency such that the switching frequency is a half integer multiple of the anode rotation frequency. This may lead to a significant reduction of the focal spot temperature.
