A Noninvasive Continuous Fetal Heart Rate Monitoring System for Mobile Healthcare Based on Fetal Phonocardiography
Although the noninvasive continuous fetal heart rate (FHR) monitor is often recommended, the Doppler Ultrasonographic Cardiotocography (CTG) is improper for long-term monitor due to the less safety and the requirement of professional operation skill. In this paper, we design a noninvasive, continuous and real-time FHR monitoring system based on fetal phonocardiography by stationary wavelet denoising and cyclostationary process. Good agreement with CTG is obtained by Bland Altman analysis. Besides, quantitative results show that the FHR has an average accuracy of 97% compared with CTG on clinical data sets. The proposed system provides an alternative for CTG.
