In a method for determining acoustic resonances in a magnetic resonance tomography system, a resonance measurement is implemented by applying a number of alternating gradient pulses that have a fixed time spacing relative to one another, applying an excitation pulse, and obtaining one or more MR signals,...http://www.google.es/patents/US6734672?utm_source=gb-gplus-sharePatente US6734672 - Method for the automatic measurement of acoustic resonance of a magnetic resonance tomography apparatus
