Abstract
Pulsed magnetic stimulation (MS) uses pulsed magnetic fields to induce electric fields (electromagnetic induction) in tissues for therapeutic purpose and is a technique that does not require surgery or external electrodes. In the previous study, our group performed in vitro experiment to examine the effects of pulsed MS on human chronic myelogenous leukemic cells. The present study demonstrated the finite element method-based numerical estimation for pulsed MS-induced magnetic and current distributions in a body in order to examine the possibility for therapeutic application of MS. The maximum induced eddy currents were 0-83.55 A/m^2 in the body and 0-25.35 A/m^2 at the pelvis by 100 mm circular coil with 1.25 T pulse magnetic field. These results were comparable with those values of cellular experiments (0 28.6-38.1 A/m^2), however, optimized coil characterization and further numerical calculation are necessary to prevent possible adverse effects (pains and muscle stimulation) induced by MS.
