Gradient induced heating

The gradient system in the MR:comp test laboratory

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 currents in conductive objects, even if these are non-magnetic, which leads to heating of the object. The measurement of gradient induced heating can be conducted in the MR:comp laboratory with gradient fields usually employed at several static magnetic field strengths, even if only the case of 1.5 T is specified by the ISO/TS 10974 standard.

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