The trend towards stronger magnetic fields and/or faster gradient switching in magnetic resonance imaging poses safety risks for patients, e.g., due to tissue heating and unwanted neurostimulation. The IEEE-ICES TC95 SC6 was formed to re-evaluate nerve excitation safety thresholds in response to temporal and spatial characteristics of electric fields induced by externally applied fields or implants. To this end, we are developing reference human anatomical models with unprecedented details in the peripheral nervous system, connectivity to organs and muscles, and functionalized with compartmental nerve models to investigate interactions with neuronal electrophysiology. We employ these phantoms to investigate current safety guidelines.
