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.

The measurements of gradient induced vibration are conducted as a research service according to the requirements described in ISO/TS 10974.
