It is a useful method to estimate the position and the current distribution of peripheral nerves with magnetic field measurement as a non-invasive inspection. A simulation study was executed to estimate the electric current sources in a nerve fiber by the magnetic fields with L1-norm method. L1-norm method using magnetic fields usually estimated scattered dipoles over the space. In case of measurement of magnetic field around a limb, approximate direction of nerve fibers is known. Therefore this study proposed a method to estimate the current dipoles in a nerve fiber in an arm or leg by selecting the direction of current dipoles resulted from L1-norm method.
