1. A method for calibrating an X-ray emitter having a cathode, an anode and a coil, wherein the coil is connected to a conductor arrangement through which an electrical function current is guided through the coil, the method comprising:
measuring an induction current that is induced in the coil at the conductor arrangement of the coil by an external magnetic field;
calculating a compensation current for an effecting coil of the X-ray emitter based on the measured induction current, the effecting coil configured to change an electron beam between the cathode and the anode, wherein the compensation current is calculated such that the external magnetic field that induces the induction current during the measuring is compensated using a magnetic field that is produced by the compensation current in the effecting coil; and
applying the compensation current in the effecting coil.
