Development of Ultrasound-Guided Transabdominal Fetal Electroencephalography

This is a feasibility study to determine whether transabdominal electrodes placed on the maternal abdomen surface can pick up fetal electroencephalography (FEEG) at different time points in pregnancy. In this proposal, we are going to develop the clinical protocol for transabdominal FEEG (TA-FEEG) recordings and the signal processing platform to reliably extract FEEG signals.
