Advances in Electromagnetic Fields in Living Systems, published by Springer since 1994, presents state-of-the-art discussions in electromagnetism that influence the activities of living organisms. This focus affirms Springer's commitment to publish important reviews to add to the scientific and professional literature significant research larger in scope than journal articles. Advances in Electromagnetic Fields in Living Systems , Volume 4 begins with fetal magnetocardiography (fMCG), a noninvasive method of detecting components of the magnetic field produced by the electrical activity of the fetal heart. FMCG is experiencing steady growth, and is expected to gain influence in diagnosing certain congenital fetal heart defects while at the same time providing optimal care for patients. FMCG provides a distinct signal, free of maternal cardiac interference, which can be detected throughout the last half of pregnancy. Other Key Topics: -Noninvasive biomedical application of non-ionizing electromagnetic energy, -Microwave thermoelastic imaging uses microwave-pulse-induced thermoelastic pressure waves to form planar or tomographic images, -Mechanisms of light-tissue interaction in the near infrared region and different types of instruments used for diffuse optical imaging, -Advances in reliable laser diodes and optical telemetry, -ELF magnetic-field exposure and the pain system, -Cyclotron resonance in enhancing the sensitivity of biological systems to magnetic fields. Advances in Electromagnetic Fields in Living Systems will be essential reading for all academics, bench scientists, and industry professionals wishing to take advantage of the latest and greatest in this continuously emerging field.
