Abstract (en)
[origin: WO2008101470A1] The aim of the invention is to produce an x-ray computed tomography arrangement in which there is no axial offset between the path of the focal spot and the x-ray detector arc. Said aim is achieved by: - arranging the x-ray detector arc (2) and the target (1) around the examination cross-section within a radiation plane such that the x-ray focal spots generated by the deflected electron beam (3) of the electron beam generator (6) lie within an axial plane, the radiation plane (5), along with the active detector elements; - disposing the x-ray detector arc (2) behind the target (1) in a radial direction such that each imaginary x-ray extending from a focal spot position on the target (1) to a detector element of the x-ray detector arc (2) penetrates the target (1), which lies in front of the point of incidence on the x-ray detector arc (2) in the direction of radiation, in the area in which the target (1) and the x-ray detector arc angularly overlap; - producing the target (1) from a target member (7) which is preferably made of a material that has a low atomic number and great heat storage capacity or thermal conductance; - applying an electron-decelerating material layer (8), preferably made of a refractory material that has a high atomic number, to the side of the target member (7) which faces the electron beam.
