Abstract

The invention discloses an ultrasonic Doppler fetal heart rate data acquisition method, device and medical equipment, belonging to the technical field of computer applications. The method includes: transmitting an ultrasonic pulse signal, generating a demodulation signal having a frequency offset relative to the ultrasonic pulse signal according to the transmission frequency of the ultrasonic pulse signal, and using the demodulation signal to demodulate the received ultrasonic echo signal An ultrasonic Doppler frequency deviation signal is obtained, and fetal heart rate data is obtained by extracting a maximum frequency envelope from the ultrasonic Doppler frequency deviation signal. In addition, an ultrasonic Doppler fetal heart rate data acquisition device and medical equipment are also provided. The above ultrasound Doppler fetal heart rate data acquisition method, device and medical equipment can simply use ultrasound Doppler technology to obtain fetal heart rate data that accurately reflects the beating of the fetal heart.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a method, device and medical equipment for acquiring fetal heart rate data by ultrasound Doppler. Background technique [0002] Fetal heart rate detection is of great significance in clinical diagnosis. By detecting fetal heart rate, it can help to improve the quality of fetal delivery and reduce the fetal malformation rate. By analyzing the fetal heart rate data after acquiring the fetal heart rate data, the monitoring of the fetal heart rate is realized. When using ultrasound Doppler technology to obtain fetal heart rate data, the frequency is The ultrasonic pulse signal is transmitted to the abdomen of the pregnant woman, and the ultrasonic pulse signal will be reflected when it encounters the heart wall of the fetus. If the heart wall moves relative to the transmitting source, the reflected ultrasonic echo signal will have a frequency change relative to the in...
