Arrangement and method for active vibration damping within an X-ray radiator

A tomography system comprising:

• an x-ray radiator and a radiation detector mounted for rotation around a system axis to generate tomographic data by irradiating an examination subject with x-rays and detecting the x-rays attenuated by the subject;
• and
• said x-ray radiator comprising a radiator housing, a plurality of components within said radiator housing, said plurality of components being configured to operate to generate said x-rays, and at least one of said components causing operational vibration during operation of said at least one component, and a counter-vibration generation unit in said radiator housing that at least reduces said operational vibration, said counter-vibration generation unit being in active connection with at least one of said radiator housing and at least one of said components and configured to generate a counter-vibration that is phase-shifted by 180° with respect to said operational vibration.
