## Abstract An important source of MRI acoustic noise—magnet cryostat warm‐bore vibrations caused by eddy‐current‐induced forces—can be mitigated by a passive metal shield mounted on the outside of a vibration‐isolated, vacuum‐enclosed shielded gradient set.

## Abstract We have designed and constructed a quiet gradient set with restricted access for the combined purposes of evaluating the principles of active acoustic screening, recently introduced by Mansfield, Glover, and Bowtell, and for EPI studies of the head at 3.0 T. The design utilizes the retu
