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.

An x-ray tube casing is provided which includes a housing having a heat exchanger integrally formed thereon in an additive manufacturing process. The additive manufacturing process allows for tight tolerances with regard to the structure for the casing and the internal passages of the heat exchanger to significantly reduce the size and weight of the casing. The casing additionally includes a fluid distribution manifold that effectively distributes the cooling fluid within the casing to more efficiently provide cooling to the x-ray tube insert disposed within the casing.
