  • Title: A new algorithm for detecting fetal heart rate using ultrasound Doppler signals.
    Author: Hua X, Kaiqing L, Zhenxi Z.
    Journal: Ultrasonics; 2005 May; 43(6):399-403. PubMed ID: 15823314.
    Abstract:
    Although the fetal heart rate monitoring using ultrasound is widely used it is still not optimized for automatic measurements due to the complexity of the Doppler signal. This paper presents a new fetal heart rate (FHR) detecting algorithm, using sampling auto-correlation approach. The results obtained using the custom-built ultrasonic Doppler fetal heart rate monitoring system are presented and confirm the validity of the method.
