fetal movement detection method, fetal movement detection device and non-transitory computer-readable media

摘要

it is a method (100) of fetal movement detection that includes: deriving a plurality of peaks from the captured doppler ultrasound signal from an individual, each peak of the plurality of peaks being associated with an envelope of a signal segment of the doppler ultrasound signal; calculate a peak density as a function of the plurality of amplitude grids, the density indicating the number of peaks with amplitude in each amplitude grid; select a fetal movement threshold based on the calculated density and determine whether a signal segment of the doppler ultrasound signal includes fetal movement by comparing the peak amplitude that is associated with the signal segment envelope with the fetal movement threshold.
