Umbilical and Uterine Artery Measurement

(A) Representative image of the typical wave shape of the umbilical artery.

(B) Representative image of the typical wave shape of the uterine artery.

(C) Study Management window for selecting ultrasound videos to measure velocity and heart rate.

(D) User interface showing the icons for measuring velocity and heart rate.

(E) Representative measurement of the umbilical artery peak systolic velocity, end diastolic velocity, and fetal heart rate.

(F) Representative measurement of the uterine artery peak systolic velocity, end diastolic velocity, and maternal heart rate.

(G) Representative data output from maternal-fetal evaluation experiment. GA, Gestational Age; HR, Heart Rate; PSV, Peak Systolic Velocity; EDV, End Diastolic Velocity; PI, Pulsatility Index; RI, Resistance Index.
