1. A method of applying electromagnetic energy to a target, comprising:
- moving a coil relative to the target; and
applying current to the coil from a plurality of locations to direct magnetic fields to the target and magnetically stimulate the target, wherein the current is applied to the coil at a sufficiently rapid frequency prevent re-polarization of the target as the coil is moved, such that the magnetic stimulation of the target is higher at the target than at a region interposed between the target and the coil.

Abstract
Techniques for applying electromagnetic energy to deep, targeted areas without overwhelming other areas are provided. One or more coils are moved relative to a target area and magnetic fields are applied to the target from multiple coil locations. As a result, the aggregate electromagetic energy applied to the target over time is greater than surrounding areas. Additionally, a model for testing and treatment planning is provided.

12. A method of applying electromagnetic energy to a target, comprising:
-
magnetically stimulating a neuronal target from a first location by applying current to a coil; moving the to a second location relative to the target; continuing the magnetic stimulation of the neuronal target from the second location by applying current to the coil, wherein the magnetic stimulation is greater at the target than the magnetic stimulation at a region interposed between the target at the coil; wherein the current applied to the coil at the first and second locations is applied at a frequency sufficient to prevent re-polarization of the target as the coil is moved. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of applying electromagnetic energy to a target brain region, comprising:
-
magnetically stimulating a target brain region by applying current to a coil from a first location; moving coil relative to the target brain region; and continuing to magnetically stimulate the target brain region by applying current to the coil when the coil is at a second location to direct magnetic fields to the target brain region, wherein the magnetic stimulation is applied at a frequency sufficient to prevent re-polarization of the target brain region as the coil is moved, such that the magnetic stimulation over time at the target brain region sums and is higher at the target brain region than at brain regions interposed between the target brain region and the coil. - View Dependent Claims (24, 25)
