Early detection of fetal neurological disorders is of significant importance however, accessing the fetal brain signal has been a challenging issue. With highly sensitive Superconducting Quantum Interference Device (SQUID) sensors, fetal magnetoencephalography (fMEG) can be recorded and there have been many studies on understanding fetal brain activity through fMEG. The major problem about fMEG data is its low signal to noise ratio. fMEG is extracted from the mixture of maternal heart, fetal heart, fetal brain, and other biological signals from mother and the fetus. Effective removal of interferences is crucial in detecting the low amplitude fetal neurological signals. The objective …

An in-utero neurological assessment would aid clinicians in an early detection of fetal neurological distress. However, accessing the fetal brain signal has remained a major challenge. With the advent of Superconducting Quantum Interference Device (SQUID) technology, magnetoencephalogram (MEG), is now an established technique for recording human brain activity. This technique is non-invasive and records the magnetic fields corresponding to electric currents generated by the neurons in the brain. Based on MEG technology, a first-of-a-kind device, named SARA (SQUID Array for Reproductive Assessment), was specifically designed and installed in the Department of Obstetrics and Gynecology, University of Arkansas for Medical Sciences, …

Theses and Dissertations
Magnetoencephalography (MEG) is widely used to study magnetic fields generated by the electrical activity of the human brain and can also be applied for fetal neurological health assessment. The fetal MEG (fMEG) signals are often contaminated with other bio-magnetic signals such as fetal breathing movement (FBM), which acts as an interfering factor for fetal neurological signals. This study was carried out to identify the bio-magnetic signals pertinent to the FBM. The fMEG signals were captured using superconducting quantum interference devices (SQUIDs) and the FBMs were recorded by an ultrasound-based video technique. The simultaneous recording is challenging since SQUIDs are extremely …
