METHOD AND AN APPARATUS FOR THE MEASUREMENT OF MAGNETIC FLUX DENSITY AND AN INDUCED CURRENT IN A MAGNETIC NERVE STIMULATOR THROUGH DETECTION OF INDUCTION VOLTAGE FROM A 3D DETECTION COIL

摘要

PURPOSE: A method and an apparatus for the measurement of magnetic flux density and an induced current in a magnetic nerve stimulator are provided to efficiently measure the magnetic flux density and induction current of a magnetism nerve stimulator by detecting induction voltage from a 3D detection coil.;CONSTITUTION: In a method and an apparatus for the measurement of magnetic flux density is comprised of the steps: determining the radius of a detection coil and the number of winding; determining the constellation of a 3D grid structure as the 3D constellation of the detection coil; determining the direction of the detection coil in vertical direction to a coordinate axis; detecting the 3D induction voltage from the signal of the detection coil; and generating 3D magnetic flux density from the detected 3D induction voltage.;COPYRIGHT KIPO 2011
