An x-ray emitter housing includes a first housing part and a second housing part that are connected to one another in a form-fit manner using an axially acting threaded ring.

X-ray emitter housing

An arrangement for the active vibration compensation of an x-ray emitter includes a counteracting vibration generation unit arranged outside of the x-ray emitter for reducing a vibration produced during operation of the x-ray emitter. The counteracting vibration generation unit is actively connected to the x-ray emitter and generates a counteracting vibration that is phase-shifted by 180 degrees relative to the vibration. By attaching active counteracting vibrators in the vicinity of the vibration generator, vibrations generated by the x-ray emitter are directly reduced at the source. A further transfer of vibrations to other system parts such as a C-armis reduced and/or prevented.

Arrangement and method for the active vibration dampening of an x-ray emitter from outside of the x-ray emitter

A method for asynchronous operation of a rotary anode of an x-ray emitter, where a torque is exerted onto the rotary anode by an electromagnetic alternating field of a stator with a first frequency is provided. The method includes increasing the first frequency to a second frequency. The second frequency is a whole number multiple of an x-ray trigger frequency. The method also includes simultaneously changing an output of the alternating field such that a rotational frequency of the rotary anode remains unchanged.
