1. Apparatus, comprising:

  • an X-ray tube, which comprises an X-ray window and is configured to direct an electron beam onto an anode so as to emit an X-ray beam through the X-ray window;

    X-ray optics, which are mounted externally to the X-ray tube with a mechanical misalignment relative to the X-ray tube, and which are configured to receive the X-ray beam emitted from the X-ray tube through the X-ray window, and to direct the X-ray beam onto a target;

    one or more coils, which are configured to steer the electron beam in the X-ray tube using electrical currents flowing through the coils; and

    control circuitry, which is configured to;

    determine, based on the X-ray beam output by the X-ray optics, respective values of the electrical currents that, when flowing in the coils, steer the electron beam to a region of the anode that causes the X-ray beam to compensate for the mechanical misalignment between the X-ray tube and the X-ray optics; and

    set the electrical currents to the determined values.
