Objectives

Narrative objectives1

We will conduct exploratory research on a new technique to extract and accurately separate fetal cardiac and fetal electroencephalographic signals simultaneously using raw data of biological signals collected by the maternal abdominal wall guidance method in clinical studies and clinical trials conducted in the past at Tohoku University Hospital.

Assessment

Primary outcomes

Frequency spectrum analysis is performed to confirm that the results extracted from the RAW data of biological signals by the maternal abdominal wall induction method are fetal-derived EEG signals. In addition, the fetal heart rate obtained at the same time is evaluated.
In addition, the stage of sleep of the fetus is estimated from the fetal heart rate chart obtained at the same time, and the relationship with EEG is examined and evaluated.

Other related information

From the RAW data obtained by the maternal abdominal wall induction method, we separate the fetal-derived biological signals using the existing fetal electrocardiogram analysis algorithm (BSSR) and perform frequency spectrum analysis. In addition, these results are checked for the presence of EEG-specific frequency bands (e.g., gamma, delta, theta, alpha, beta, etc.) and used as supervisory data for time series AI.
Then, only the fetal-derived bio-signals are separated from the raw data induced by maternal abdominal wall guidance using the existing fetal ECG analysis algorithm as well. Here, the EEG signal is separated from the fetal-derived bio-signal using the trained time series AI.
