We present the design considerations and evaluation measurements for the safety of a PatLoc (Parallel Acquisition Technique using Localized Gradients) gradient insert coil designed for human head imaging on a 3T MRI system. This novel concept has the potential to allow higher gradient switching rates while not exceeding the Peripheral Nerve Stimulation (PNS) limits. Based on the presented experimental measurements and simulations, we consider imaging human volunteers with this system to be safe.
