Abstract
Methods and systems for modeling and displaying magnetic field intensities during Transcranial Magnetic Stimulation (TMS) are described, particularly methods and system for modeling and displaying TMS using overlapping magnetic fields to stimulate deep brain regions.
Claims11
A method of generating a Transcranial Magnetic Stimulation (TMS) treatment plan for a patient, the method comprising the steps of:
- displaying representations of a plurality of TMS electromagnets around a model of the patient's brain;
- calculating the intensity of the magnetic field for a plurality of brain regions including a deep brain target based on the positions of the TMS electromagnets relative to the brain and based on pre-computed magnetic field models for each of the plurality of TMS electromagnets;
- displaying the magnetic field intensity at the deep brain target on the model of the patient's brain and on non-target regions in the patient's brain;
- and
- moving the representation of at least one TMS electromagnet and re-calculating the intensity of the magnetic field for the deep brain target until the magnetic field intensity at the deep brain target is above a stimulation threshold while the magnetic field intensity at non-target regions is below a stimulation threshold.
