Quadruple butterfly coil

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.

MULTI-SPHERE HEAD MODEL FOR DIPOLE LOCALIZATION

In one aspect, a computer-implemented method corrects a multi-sphere head model used in dipole localization for a set of magnetic field sensors (MEG sensors) by replacing ghost spheres with replacement spheres that are not ghost spheres. One type of ghost sphere completely encloses the brain volume but is so large that a center of the sphere is outside the brain volume. Another type of ghost sphere lies entirely outside the brain volume. Various approaches for correcting ghost spheres are disclosed.
