New Horizons in Electromagnetics in Medicine and Biology

Forty years of studies on bioelectromagnetics, in our laboratory, are presented to view new horizons in electromagnetics in medicine and biology. The several topics are reviewed and discussed. The review includes transcranial magnetic stimulation (TMS) of the human brain, imaging of electrical information in the brain based on magnetic resonance imaging (MRI) such as impedance MRI and current MRI, cancer therapy using magnetizable beads and pulsed magnetic fields, magnetic control of cell orientation and cell growth, and effects of radio frequency electromagnetic fields on iron ion release, and uptake from and into iron cage proteins, ferritins. These techniques are leading medicine and biology into a new horizon through the novel applications of magnetism and electromagnetics. Key Points Transcranial magnetic stimulation with a figure‐eight coil for localized stimulation and deep brain stimulation by different coil configurations are proposed Imaging of electrical information using magnetic resonance imaging is proposed. These are magnetic resonance‐based electric impedance and current imaging Cancer cell destruction, bone growth acceleration, iron release, and uptake from and into cage proteins, ferritins, are modulated by electromagnetic fields
