Table 1.

Modeled primary and total E-field vector components for the B-shaped TMS coil in various phantom and head models. Values are modeled for a TMS stimulator setting of 50% and are reported in V m⁻¹. These values were taken at (X = 0 mm, Y = 0 mm, Z = 30 mm) in each model unless otherwise noted.
