摘要：

An approximate distance between an ultrasonic transducer and a fetal heart is determined. A range of distances from the ultrasonic transducer is sensed using the ultrasonic transducer, wherein the range has a minimum distance based upon the approximate distance. A heart rate of the fetal heart is monitored using ultrasonic echo signals from the range.
