由超声多普勒频移信号估计胎心率算法探讨

Discussion about the algorithms on estimating the foetal heart rate from the ultrasonic Doppler signal

胎心率监护在临床医学中具有重要参考价值。采用超声多普勒技术进行无创监护是目前临床使用最为广泛的监护手段之一。为了能够从多普勒频移信号中准确的估计瞬时胎心率,国内外在算法思想和算法实现领域进行了长期和较为广泛的研究。本文将研究过程中了解到的各种算法思想和算法实现进行了归纳与探讨。

It is definitely important that the foetal heart rate should be clinically monitored. And the method with ultrasonic Doppler is popular. Because ultrasound brings little hurt to the foetus. In order to estimate the FHR inerrably, research on the algorithms is deep. This paper presents some algorithms in the studies.
