Method and System for Displaying the Electric Field Generated on the Brain by Transcranial Magnetic Stimulation
First Claim
1. A method for generating a representation of a portion of a brain for use in transcranial magnetic stimulation (“
- TMS”
) comprising;
generating an actual representation of a head surface of a head;
generating an idealized representation of the head surface;
combining the actual and idealized representations to form a visualization surface, wherein the visualization surface is representative of a portion of the brain within the head at a depth beneath the head surface; and
displaying the visualization surface.

Abstract
A visualization surface representative of a portion of the brain at a depth below the head surface of the subject is generated by combining an actual representation of the head surface with an idealized representation of the head surface. The combining is a function of the depth and is performed to minimize in the visualization surface any irregularities existing in the actual head surface of the subject. A display shows the visualization surface overlaid on a volumetric image of the brain, the electric field induced on a region of the visualization surface by a transcranial magnetic stimulation (“TMS”) induction coil device positioned above the head surface and the TMS coil device. By viewing the display, a user of the TMS coil device can interactively position the TMS coil device in relation to the head surface and, for a target site on the brain at a selected depth, determine the position at which the TMS coil device induces a maximum E-field on a visualization surface corresponding to the selected depth.
