1. A method of modeling Transcranial Magnetic Stimulation (TMS) on a deep brain target, the method comprising:
- arranging representations of a plurality of TMS electromagnets around a model of a patient'"'"'s head, wherein each TMS electromagnet has a pre-computed magnetic field model;
calculating the intensity of the magnetic field at each of a plurality of brain regions by summing the magnetic field intensities of the portions of the pre-computed magnetic field model for each TMS electromagnet at each brain region; and
displaying the calculated magnetic field intensities for each of the plurality of brain regions.

9. 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 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 electrode 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. - View Dependent Claims (10, 11, 12, 13)
