Comparison of Peak Simulated Electric Fields with PNS Locations

Gradient coil induced electric fields are simulated in a Visible Man model of a human male head, neck, and torso. The simulation indicates that tissue geometry plays a large role in the magnitude of the field experienced. In addition to large fields accumulating at locations on the surface of the body, such as the tip of the nose, internal air cavities also demonstrate enhanced electric fields. The locations of large simulated electric field include the sinus cavities as well as an air cavity in the chest. These locations of high simulated field are compared to the locations of actual stimulation.
