As gradient engineering advances, Peripheral Nerve Stimulation (PNS) increasingly limits MRI gradient coil use. The ability to predict a winding pattern’s PNS threshold could be useful during design iteration, but recently introduced methods for simulating the threshold in full body models including nerve atlases and neurodynamic simulations are computationally slow. Here we present a simple PNS oracle which is linear (with respect to the E-field) that allows prediction of the gradient-induced stimulation threshold without relying on full neurodynamic modeling. We validated the fast oracle against the full neurodynamic model in multiple gradient coils and two body models.
