DETERMINATION OF OPERATIONAL STATE OF X-RAY SOURCE

Abstract: a method at an x-ray source is disclosed, the x-ray source comprising an electron source for providing an electron beam and a target comprising a first working region for generating x-ray radiation upon interaction with the electron beam. the method comprises determining a first quantity indicative of a current absorbed by the target at the first working region, and in response to the first quantity deviating from an expected value moving the electron beam from the first working region to a reference region, determining a second quantity indicative of a current absorbed at the reference region, and determining an operational state of the x-ray source based on the first quantity and the second quantity, wherein the operational state is an electron beam fault state or a target fault state.
