SYSTEM AND METHOD FOR IDENTIFYING HIGH RISK PREGNANCIES

摘要

Method system and software product for identifying high risk pregnancies comprising the step of generating a spectrogram from ultrasound Doppler signals reflected from the uterine artery and determining the maximum frequency envelope of said spectrogram and of defining a systolic part and a diastolic part of the maximum frequency envelope and calculating an area ratio under said systolic and diastolic part (AR). This area ratio relates to the blood volume in the uterine artery.
