Design of a Light Stimulator for Fetal and Neonatal Magnetoencephalography

摘要

The design, safety analysis, and performance of a fetal visual stimulation system suitable for fetal and neonatal magnetoencephalography studies are presented. The issue of fetal, neonatal, and maternal safety is considered and the maximum permissible exposure is computed for the maternal skin and the adult eye. The risk for neonatal eye exposure is examined. It is demonstrated that the fetus, neonate, and mother are not at risk.
