    • 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.
    • 本发明公开了用于控制磁场和磁场感应电流的方法和系统,更具体地,以非侵入性方式提供患者体内的刺激,例如深部脑刺激,并且具有比已经提供的更大的焦点和控制 通过先前已知的方法和系统。 根据实施例的某些方面,提供磁性线圈阵列并且围绕患者身体的一部分定位。 在操作期间,至少一些磁性线圈用作被配置为产生DC磁场的DC线圈对,而其他磁性线圈的至少一些DC线圈用作瞬态磁场发生器,以在该部分内产生感应电流 患者的身体,如患者大脑的区域。 该系统被配置为使得DC磁场可以用于操纵瞬态磁场,反过来允许在患者身体内的特定期望的感兴趣体积内显着改善感应电流的控制和聚焦。
