Beamscanning probe antennas for Deep Brain Stimulation

The surgery techniques for Deep Brain Stimulation (DBS) has been sufficiently improved; it is again being used in patients with advanced Parkinson Disease (PD) or medication is no longer effective [1, 2]. DBS consists of an implanted pulse generator (IPG) or brain pacemaker, the lead and the extension [3]. IPG is usually located near the shoulder blade and supplies electrical pulses to the lead through the extension. The lead is an electrode, which radiates electromagnetic wave on specific areas, such as substantia nigra, of the brain. The radiation will actuate the brain to produce dopamine. Dopamine can alleviate PD patents' motor symptoms.
