Consideration for Magnetic Sources on Magnetospinography(Application)

Abstract

Nerve actions generate current distribution and evoke magnetic field outside the body. Magnetospinography (MSG) visualizes signal transfer on spinal cord by measuring and analyzing magnetic field evoked by the signal transfer. It can be used in localization of spinal cord damage. This paper treats some problems on the existing model for magnetic sources on MSG and reveals the cause of the problems. Furthermore, the author proposes a new model and shows its superiority over existing one.
