Abstract

Described herein are Transcranial Magnetic Stimulation (TMS) systems and methods configured to focus the applied magnetic fields generated by one or more primary TMS electromagnets using attractor magnets and/or magnetic concentrators having high-permeability regions. An attractor magnet is typically a secondary, phase-complimentary magnet that is configured to shape the field of the primary TMS electromagnet. A magnetic concentrator typically includes a region of high magnetic permeability that may shape a TMS magnetic field. Attractor magnets and concentrator devices can be used independently or in combination. The profile of the TMS field can be made narrower or wider than for an unfocused field using these devices, systems and methods.
