X-RAY SOURCE APPARATUS, COMPUTER TOMOGRAPHY APPARATUS, AND METHOD OF OPERATING AN X-RAY SOURCE APPARATUS

摘要

An X-ray source apparatus (100) comprises a cathode (101), comprises an electron beam deflection means including one or more electron beam deflection elements (103) and comprises an anode (102). The cathode (101) is adapted to emit an electron beam (104) towards the electron beam deflection means. The electron beam deflection means is adapted to deflect an electron beam (104) coming from the cathode (101) to a selectable part (110) of the anode (102), wherein the selectable part (110) of the anode (102) is selectable to by activating a single one of the one or more electron beam deflection elements (103), with the single activated electron beam deflection element (103) being arranged at a variable position along a propagation path of the electron beam (104) coming from the cathode, (101) such that the electron beam (104) is deflected to the selectable part (110) of the anode (102). The anode (102) is adapted to generate an X-ray beam (104) when being irradiated by an electron beam (104) deflected by the electron beam deflection means.
