X-ray tube assembly for X-ray apparatus for receiving X-ray image of examined object, has sheet-shaped X-ray source and sheet-shaped formed anode which is irradiated with electron beam generated in cathode

摘要

#CMT# #/CMT# The X-ray tube assembly (20) has a sheet-shaped X-ray source and a sheet-shaped formed anode (16) which is irradiated with an electron beam (18) generated in a cathode (17) and is stimulated for emitting an X-ray irradiation (13). The electron beam is deflected and controlled such that it scans a part of the anode surface of the anode, in order to generate a planar radiating surface of the x-ray irradiation. A collimator (15) is formed for parallelizing the resulting X-ray irradiation. #CMT# : #/CMT# Independent claims are included for the following: (1) an X-ray apparatus with an X-ray detector; and (2) a method for operating an X-ray tube assembly. #CMT#USE : #/CMT# X-ray tube assembly for X-ray apparatus for receiving an X-ray image of an examined object (Claimed). #CMT#ADVANTAGE : #/CMT# The X-ray tube assembly has a sheet-shaped X-ray source and a sheet-shaped formed anode which is irradiated with an electron beam generated in a cathode and is stimulated for emitting an X-ray irradiation, and thus ensures improved X-ray tube assembly, which enables a beam homogenization in dependence on the dynamics of the examined object. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an X-ray tube assembly. 13 : X-ray irradiation 15 : Collimator 16 : Anode 17 : Cathode 18 : Electron beam 20 : X-ray tube assembly.
