Latest Patents

One of Johannes Walk's latest patents is a method and apparatus for heating current control of a pulsed X-ray tube. This innovation provides a way to control the heating current flowing through the emitter of a pulsed X-ray tube during pulse pauses. The method involves comparing a measured actual value of the heating current with a predefinable desired value. A low-pass filtering of the actual value is performed before the comparison, ensuring that the heating current control does not interfere with tube current control during pulses.

Another significant patent involves the asynchronous operation of a rotary anode with reduced focal spot shake. This method exerts torque onto the rotary anode using an electromagnetic alternating field of a stator at a specific frequency. The frequency is increased to a whole number multiple of an X-ray trigger frequency while maintaining the rotational frequency of the rotary anode.
