Abstract :
Several recent studies have demonstrated the usefulness of fetal magnetocardiogram (fMCG) actography, a relatively new method of detecting fetal movement that can be performed in conjunction with fMCG assessment of fetal heart rate and rhythm. In this study, we formulate indices of fetal activity that incorporate information from all channels to achieve improved sensitivity. We also utilize statistical detection to provide an objective means of inferring significant fetal activity.
