# Efficient fetal-maternal ECG signal separation from two channel maternal abdominal ECG via diffusion-based channel selection

## TL;DR

This paper introduces a diffusion-based channel selection algorithm for accurately separating maternal and fetal ECG signals from just two abdominal channels, aiming to improve affordable fetal monitoring.

## Contribution

The paper presents a novel mathematical formalism and clinical validation of a diffusion-based method for fetal-maternal ECG separation from minimal two-channel data.

## Key findings

- Effective separation of maternal and fetal ECG achieved
- Validated through clinical data
- Potential for low-cost fetal monitoring

## Abstract

There is a need for affordable, widely deployable maternal-fetal ECG monitors to improve maternal and fetal health during pregnancy and delivery. Based on the diffusion-based channel selection, here we present the mathematical formalism and clinical validation of an algorithm capable of accurate separation of maternal and fetal ECG from a two channel signal acquired over maternal abdomen.
