Synopsis:
All electrophysiological phenomena are characterized by the flow of ion currents within the body. The physics of electromagnetism predicts that the flow of current will also result in a magnetic field. SQUID (Superconducting Quantum Interference Device) sensors are capable of detecting minute magnetic field fluctuations. Based on this technology a recording technique called Magnetoencephalography (MEG) has evolved and is used to record the brain activity from a human adult. We have modified this technology to build a device called SARA (SQUID Array for Reproductive Assessment) to assess fetal well-being. The SARA device is equipped with 151 SQUID sensors with the array curved to fit the shape of a pregnant abdomen. The overall goal of this project is to provide a non-invasive means to monitor the electrophysiology of the developing fetus and improve the diagnostic capability. We record fetal cardiac and neurological signals starting at 28 weeks of pregnancy. The talk will focus on the design aspects of the SARA MEG system and discuss the recording, analysis and interpretation of fetal cardiac, auditory and visual evoked brain response signals.

Biography:
Dr. Eswaran received his BSc and MSc in Physics (Electronics) from the University of Delhi, India. He also received his MS in Physics (Acoustics) from the University of Mississippi, USA and his doctoral degree in Applied Sciences (Biomedical Instrumentation) from the University of Arkansas at Little Rock, USA. His doctoral work was titled, “Fetal Auditory Evoked potentials
and Fields”. Currently he is an Assistant Professor and SARA Lab Director in the Department of Obstetrics and Gynecology. His area of research is focused on biomedical instrumentation
with special emphasis on fetal monitoring instrumentation. He is Co-Investigator in a project funded by National Institutes of Health to design and acquire Fetal Evoked Biomagnetic Fields using both light and auditory stimulus with a 151 channel magnetic field sensor array. His general areas of research include - fetal and newborn evoked potentials, magnetoencephalography (MEG), electro and magnetomyography, acoustics, signal processing and electronics.
Dr Eswaran is a Member of the Editorial Review Board for international journal “Applied Acoustics” and reviewer for international journal "Particulate Science and Technology" and Experimental Neurology Journal. He won Young Investigator Travel Grant Award by Acoustic Society of America in June 2001; Central Association Award for the Best OB/GYN research poster presentation 1998 at the 66th Annual CAOG in Kansas City, MO; M. K. Testerman Award for Outstanding Research in Biomedical Instrumentation 1997, University of Arkansas at Little Rock; and Dean's Honor List, College of Science and Engineering Technology (August 1993-May 1998), UALR. Dr Eswaran has published over
50 technical papers in peer-reviewed journals and conferences.
