| Research Abstract |
Fetus magnetocardiograph which did not require the magnetically shielded room was developed. The fetus magnetocardiograph is using the low noise and wide range type analog control circuit. The fetus magnetocardiogram is weak signal, and it is measured in the condition that was buried in the noise. Then, noise rejection program using the independent component analysis and the Wiener filter was made. The extraction of the fetal heart rate fluctuation became possible. And, features of heart rate variability of the fetus which changed with the pregnancy progress were confirmed.
