METHOD AND APPARATUS FOR MONITORING FETAL HEART RATE AND SOUND USING A MULTI-CHANNEL DOPPLER EFFECT

摘要

PURPOSE: An apparatus and a method for detecting fetus heart sound and heart rate using multi-channel doppler are provided to detect a sound source within a short period of time by using ultrasonic sensors of N number to track a position of a transmitting and receiving sensor module. CONSTITUTION: An apparatus for detecting fetus heart sound and heart rate using multi-channel doppler includes an ultrasonic probe array(90), a channel selector(70), a beam forming module(30), and a microcomputer controller(10). The ultrasonic probe array(90) is formed with a plurality of ultrasonic probes to detect a sound source. The channel selector(70) is used for providing an ultrasonic wave to the ultrasonic probe array and controlling the ultrasonic probe array by collecting ultrasonic signals. The beam forming module(30) is used for extracting noiseless signals by averaging the collected ultrasonic signals. The microcomputer controller(10) extracts a position of the sound source and a generation signal by controlling the channel selector and the ultrasonic probe array.
