Synopsis

Keywords: Safety, SafetyA large region of linearity in whole-body gradient coils exposes large body areas to switching magnetic fields, inducing high electric fields, which may cause peripheral nerve stimulation. A body gradient array coil (made up of multiple coil elements) can produce linear gradients in different region of linearity shapes by optimizing the feeding currents, which can minimize the induced E-fields.
