Blood flow and blood velocity measurement in vivo by electromagnetic induction
Transactions of the Institute of Measurement and Control, 1982The application of electromagnetic induction to the measurement of blood flow and blood velocity in vivo is reviewed, The electronic requirements are discussed and the associated problems are surveyed. A brief account is given of Bevir's virtual current theory and its application to flow and velocity measuring devices.

Estimating Blood Flow Velocity in Liver Vessels
2009Orthogonal polarization spectroscopy (OPS) is a technique for taking images to finally characterise microcirculation. Current image analysis algorithms have limitations when applied to image sequences obtained from the liver. We developed an automatic analysis tool which enables detection of liver vessels, measurement of vessel diameters, and ...

Effects of aging on cardiac blood flow velocities
Journal of Clinical Ultrasound, 1988AbstractThe effects of aging on cardiac blood flow velocities are important as a description of the natural history of the aging process and as a reference for evaluation of the aging cardiovascular system. We therefore studied these effects in 215 healthy volunteers, 120 males and 95 females, between 1 and 65 years old.

Astaxanthin increases choroidal blood flow velocity
Graefe's Archive for Clinical and Experimental Ophthalmology, 2011Previous studies have reported that astaxanthin (AXT) has antioxidative and anti-inflammatory effects in addition to its ability to shorten blood transit times. As laser speckle flowgraphy (LSFG) can noninvasively visualize the hemodynamics of the choroidal circulation, we used the technique to evaluate whether continuous ingestion of 12 mg of AXT per ...

The Effect of Remifentanil on Cerebral Blood Flow Velocity
Anesthesia & Analgesia, 1998In the present study, we investigated the effect of remifentanil on cerebral blood flow velocity (CBFV). We investigated 20 patients (ASA physical status III) scheduled for elective coronary artery bypass graft surgery. Anesthesia was induced with remifentanil 5 microg/kg IV (Group 1, n = 10) or 2 microg/kg IV (Group 2, n = 10) and was maintained with ...

Effect of compression stockings on venous blood velocity and blood flow
Thrombosis and Haemostasis, 2010SummaryThe effects of graduated compression stockings (GCS) on venous blood velocity have not been established. In healthy subjects, most investigations showed no effect on blood velocity, but mixed results have been reported. In this investigation we to test the hypothesis that popliteal blood velocity is increased by properly fitted GCS. Time average
