摘要： In a rotatable anode (4) of an X-ray tube, a heat transfer between the rotating disc of the anode (4a) and the second bearing element (11) is achieved by providing a contact material (14) within a gap (16a, b) between the anode disc (4a) and the second bearing element (11). Contact elements (15) protrude from the second bearing element (11) into the contact material (14), thus allowing a heat transfer from anode disc (4a) to second bearing element (11) via contact material (14) and contact element (15).

摘要： 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.

摘要： An X-ray tube (1) comprising a cathode (3), an anode (5) and a further electrode (7) is proposed. Therein, the further electrode is arranged and adapted such that, due to impact of 'free electrons (27) coming from the anode (5), the further electrode (7) negatively charges to an electrical potential lying between a cathode's potential and an anode's potential. The further electrode (7) may be passive, i.e. substantially electrically isolated and not connected to an active external voltage supply. The further electrode (7) may act as an ion pump removing ions from within a primary electron beam (21) and furthermore also removing atoms of residual gas within the housing (11) of the X-ray tube (1). In order to further increase the ion pumping capability of the further electrode (7), a magnetic field generator (61) can be arranged adjacent to the further electrode (7).

摘要： The invention relates to a computer tomography system comprising a support structure, more than one source of radiation, a detector array, and a grid, wherein the support structure defines a space to accommodate an object of interest which can be moved through the ring. The object of interest is radiographed by means of the sources of radiation which are located at the perimeter of the support structure and are movable along said perimeter. The sources are arranged displaced behind each other. The detector array is located at the perimeter of the support structure opposite the sources of radiation, and is movable simultaneously with the sources along the perimeter of the ring. The grid is arranged on the side of the detector array, orientated to the sources, to focus detector modules arranged on the detector array. By means of said CT system, improved radiographic images can be achieved from the object of interest.
