Abstract
The present invention discloses methods and systems to control magnetic fields and magnetic field induced currents, and more particularly to provide stimulations within a patient's body, such as deep brain stimulation, in a non-invasive manner and with greater focus and control than has been afforded by prior known methods and systems. In accordance with certain aspects of an embodiment, an array of magnetic coils is provided and positionable about a portion of a patient's body. During operation, at least some of the magnetic coils function as DC coil pairs configured to generate a DC magnetic field, while at least some DC coil of the other magnetic coils function as transient magnetic field generators to generate an induced current within a portion of the patient's body, such as in a region of the patient's brain. The system is configured such that the DC magnetic fields may be used to manipulate the transient magnetic fields, in turn allowing significantly improved control and focus of the induced current within a specifically desired volume of interest within a patient's body.
