Abstract: An apparatus includes an X-ray tube, X-ray optics, one or more coils and control circuitry. The X-ray tube is configured to direct an electron beam onto an anode so as to emit an X-ray beam. The X-ray optics which configured to receive the X-ray beam emitted from the X-ray tube and to direct the X-ray beam onto a target. The coils are configured to steer the electron beam in the X-ray tube using electrical currents flowing through the coils. The control circuitry is configured to compensate for misalignment between the X-ray tube and the X-ray optics by analyzing the X-ray beam output by the X-ray optics, and setting the electrical currents based on the analyzed X-ray beam.
