NEUROLOGICAL MONITORING CABLE FOR MAGNETIC RESONANCE ENVIRONMENTS

Abstract: an electrode system includes an electrode, a connector, and a cable with an in-line radio-frequency filter module comprising resistors and inductors without any deliberately added capacitance. the resistors are arranged in an alternating series of resistors and inductors, preferably with resistors at both outer ends, and connected electrically in series. the in-line module is located at a specific location along the wire, chosen through computer modeling and real-world testing for minimum transfer of received rf energy to a patient's skin, such as between 1oo cm and 150 cm from the electrode end of a 240 centimeter cable. the total resistance of the resistors plus cable, connectors and solder is 1000 ohms or less; while the total inductance is roughly 1560 nanohenries. the inductors do not include ferrite or other magnetic material and are, together with the resistors, stock components thereby simplifying manufacture and reducing cost.
