1. A method for regulating a position of an X-ray focus on an anode of an X-ray source of an X-ray imaging system, the method comprising:
determining a combined actual position of the X-ray focus by combining a measured position of the X-ray focus and a model based position of the X-ray focus, the model based position of the X-ray focus determined based on a measured value of a deflection current;
determining a manipulated variable based on the combined actual position and a target position; and
performing a regulation for correcting a deviation of the position of the X-ray focus from the target position based on the manipulated variable.
