Fetal Electrocardiogram (fECG) Gated MRI

Fetal Electrocardiogram (fECG) Gated MRI

We have developed a Magnetic Resonance Imaging (MRI)-compatible system to enable gating of a scanner to the heartbeat of a foetus for cardiac, umbilical cord flow and other possible imaging applications. We performed radiofrequency safety testing prior to a fetal electrocardiogram (fECG) gated imaging study in pregnant volunteers (n = 3). A compact monitoring device with advanced software capab...

Fetal Electrocardiogram Extraction and Analysis

Fetal electrocardiogram (ECG) for fetal monitoring during labour.

BACKGROUND Animal and human studies have shown that fetal hypoxaemia during labour can alter the shape of the fetal electrocardiogram (ECG) waveform, notably (1) the relation of the PR to RR intervals and (2) elevation or depression of the ST segment. Technical systems have therefore been developed to monitor the fetal ECG during labour as an adjunct to continuous electronic fetal heart rate mo...

Improvement of the Fetal Electrocardiogram Signals

-The health of the fetus is of major concern to both obstetricians and expectant mothers. A non-invasive fetal electrocardiogram (FECG) system can monitor fetal cardiac condition during pregnancy. However, the FECG signal is often very weak or drowned out by the mother’s ECG (MECG) and other noises. This study uses a FastICA algorithm to the isolate FECG signal from other noise interference. Th...

Fetal Electrocardiogram Extraction and Performance Analysis

In biomedical engineering, to extract the fetal electrocardiogram (FECG) exactly is a significant and challenging research topic, and so it has been a hot field in biomedical research. Now, a variety of different methods have been proposed to address this problem. From the perspective of blind signal processing, FECG extraction can be modeled as Blind source separation (BSS). In this paper, we ...
