Patent ID: 11315751

Abstract:
Disclosed herein is an apparatus for electromagnetic x-ray control. The apparatus comprises a thermionic filament, positioned at a first end of a micro-focus x-ray tube and configured to generate an electron stream. The apparatus also comprises an x-ray generation target, positioned within the micro-focus x-ray tube at a second end of the micro-focus x-ray tube, opposite the first end, to receive the electron stream and to generate x-rays in response to the electron stream impinging on the x-ray generation target. The apparatus further comprises an electromagnetic field element, configured to generate an electromagnetic field that receives the electron stream and operable to vary the electromagnetic field to redirect the electron stream, within the micro-focus x-ray tube, to impinge on the x-ray generation target at variable locations on the x-ray generation target. Each one of the variable locations corresponds to a different one of multiple variations of the electromagnetic field.
