In order to achieve higher image quality and speed, it is preferred to use high-strength, high-slew-rate gradient coils in imaging applications. The peripheral nerve stimulation (PNS), however, limits this fast gradient switching where it may result in a mild to intolerable discomfort for the patient. IEC standards put limits on the gradient output to operate in the normal safe mode. For biological tissues, the IEC standard for safe gradient switching is given by the following formula as the upper limit...
