Title:
X線コンピュータ断層撮影装置
Document Type and Number:
Japanese Patent JP5458305
Kind Code:
B2
Abstract:
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 and the target around the examination cross-section within a radiation plane such that the x-ray focal spots generated by the deflected electron beam of the electron beam generator lie within an axial plane, the radiation plane, along with the active detector elements; —disposing the x-ray detector arc behind the target in a radial direction such that each imaginary x-ray extending from a focal spot position on the target to a detector element of the x-ray detector arc penetrates the target, which lies in front of the point of incidence on the x-ray detector arc in the direction of radiation, in the area in which the target and the x-ray detector arc angularly overlap; —producing the target from a target member 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, preferably made of a refractory material that has a high atomic number, to the side of the target member which faces the electron beam.
