Perceptual and Motor Skills, 1972
A velocimeter employing secondary emission photomultipliers has been described. A softball or other light colored object is detected against a black background under room ambient light conditions. The throwing field is triangular with a useable area of approximately 30 ft 2 .

Ultrasonic Velocimetry of Biological Compounds
Annual Review of Biophysics and Biophysical Chemistry, 1991Ultrasonic 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

Middle Cerebral Artery Velocimetry: Different Clinical Relevance Depending on Umbilical Velocimetry
Obstetrics & Gynecology, 1997To 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

[Velocimetry and sympathectomy].
Journal des maladies vasculaires, 1983In a previous work, the writers have described the influence of vasomotoricity on the shape of the ultrasonic velocimetric curves (Doppler). A vasodilatation induced by an anaesthesia of the sympathetic chain or by a general anaesthesia by penthotal produces a raising of the whole curve above the basic line. The writers have studied in the present work

Ophthalmic Artery Velocimetry in Preeclampsia
Gynecologic and Obstetric Investigation, 2010Our objective was to compare ophthalmic artery pulsatility index values from normal pregnant women with those from preeclamptic patients. The ophthalmic artery of 20 normotensive pregnant women, 7 mildly preeclamptic and 2 severely preeclamptic patients was studied once with color Doppler flow imaging and pulsed Doppler ultrasonography after 32 weeks ...
