Gradient induced vibration

During magnetic resonance imaging (MRI), pulsed gradient magnetic fields are sent out from the MR scanner to the object inside the scanner. This can induce eddy current magnetic moments in conductive objects, even if these are non-magnetic. These eddy currents can interact with the static magnetic field B₀ of the MR scanner, leading to vibration of the object.

MR:comp has been officially accredited to conduct tests of gradient induced vibration according to ISO/TS 10974.
