Abstract

A magnetic resonance system includes a magnet device, which is arranged in an outer housing and an inner housing located therein. A monitoring method includes determining a value of a vibration amplitude of the outer housing or an intermediate housing located between the inner housing and the outer housing at a vibration frequency; providing a transmission ratio between the vibration amplitude and the operating parameter at the vibration frequency; and determining a value of the operating parameter as a function of the determined value of the vibration amplitude by means of the transmission ratio.
