Abstract
Provided herein are embodiments of a Quadruple Butterfly Coil (QBC) configuration having enhanced focality for stimulation of specific areas of a brain for therapeutic treatment. Finite element simulations were conducted for the QBC, the QBC with a single shield, and the QBC with a double shield. The stimulation profiles for these coil configurations were assessed with 50 anatomically realistic MRI derived head models. The coils were positioned on the vertex and the scalp over the dorsolateral prefrontal cortex to stimulate the brain. Computer modeling of the coils was performed to determine volume of stimulation, maximum electric field, location of maximum electric field, and area of stimulation across all 50 head models for both coils.
