Background: Doppler velocimetry
studies of placental and fetal circulation can provide important information regarding fetal well-being providing an opportunity to improve fetal outcome.
Antepartum foetal surveillance with amniotic fluid index measurement and Obstetric ultrasound with foetal Doppler velocimetry
was done twice a week.
1] It has been studied that Doppler velocimetry
of umbilical artery in unselected and low-risk pregnancies cannot be recommended.
in superior vena cava provides useful information on the right circulatory function in patients with congestive heart failure.
Uterine artery Doppler velocimetry
in relation to trophoblast migration into the myometrium of the placental bed.
4] However, the true clinical implications of these placental findings and Doppler velocimetry
(DV) associations are still not well established.
The predictive role of doppler velocimetry
was based on the differences found in mean uterine artery pulsatility index (PI), resistance index (RI) and peak systolic velocity (PSV), systolic/diastolic velocity ratio (S/D) values between pregnant and nonpregnant groups of women.
and non stress test in severe fetal growth restriction.
Identification of patients at risk for early onset and/or severe preeclampsia with the use of uterine artery Doppler velocimetry
and placental growth factor.
Contract notice: Supply delivery and installation of a laser Doppler velocimetry
system with a fluorescence laser-induced extension for ~ University of the harbor.
Some specific subjects explored include thin-film sensors integrated in information displays, a high-speed fluorescence imaging system for freely moving animals, ToF cameras for eye-in-hand robotics, and laser Doppler velocimetry
technology for integration and directional discrimination.
Optically capturing hundreds of time-resolved velocity records with high fidelity in a difficult environment requires both the Argus probe and the Multiplexing Photonic Doppler Velocimetry
(MPDV) system, which won an R&D 100 Award in 2012.
