Middle Cerebral Artery Velocimetry: Different Clinical Relevance Depending on Umbilical Velocimetry

Obstetrics & Gynecology, 1997
To evaluate the role of cerebral velocimetry as a predictor of perinatal outcome in high-risk pregnancies.Middle cerebral artery pulsatility index was measured in 576 high-risk pregnancies undergoing umbilical velocimetry. The results of both tests were evaluated with respect to the birth of small for gestational age (SGA) infants and adverse perinatal

Particle Shadow Velocimetry (PSV) in bubbly flows

International Journal of Multiphase Flow, 2018
The interaction of gas bubbles and the surrounding liquid in bubbly flows is a complex hydrodynamic phenomenon. Precise measurements of the liquid velocity are mandatory to generate accurate models and CFD-validation data sets.

Doppler velocimetry in pregnancy

Seminars in Ultrasound, CT and MRI, 1993
Since the late 1970s, Doppler velocimetry has been investigated extensively for use in obstetrics. Initially, this technique showed promise for the management of certain complications of pregnancy; this promise has yet to be fulfilled. Doppler velocimetry of either the uterine or umbilical vessels, which showed some merit in selecting growth-retarded ...

Ultrasonic Velocimetry of Biological Compounds

Annual Review of Biophysics and Biophysical Chemistry, 1991
Ultrasonic velocimetry, a method of molecular biological studies developed in recent years, is an effective tool for investigating hydration of biological substances, conformational transitions of biopolymers and molecular interactions. The method is based upon precise measurements of ultrasonic velocity in solutions of biological substances. The paper

Three-dimensional particle velocimetry

Measurement Science and Technology, 1994
In recent years, the problems tackled by experimentalists and theoreticians in fluid dynamics have grown considerably. Sophisticated flow facilities like large size or high speed wind tunnels are the basis for ambitious experiments, and powerful computers allow modelling of very complex flow fields.
