Principle study on the signal connection at transabdominal fetal pulse oximetry
Current Directions in Biomedical Engineering, 2016 Transabdominal fetal pulse oximetry is an approach to measure oxygen saturation of the unborn child non-invasively. The principle of pulse oximetry is applied to the abdomen of a pregnant woman, such that the measured signal includes both, the maternal ...

quEEGNet: Quantum AI for Biosignal Processing
2022 IEEE-EMBS International Conference on Biomedical and Health Informatics (BHI), 2022 In this paper, we introduce an emerging quantum machine learning (QML) framework to assist classical deep learning methods for biosignal processing applications. Specifically, we propose a hybrid quantum-classical neural network model that integrates a variational quantum circuit (VQC) into a deep neural network (DNN) for electroencephalogram (EEG ...
