Biometric, B-mode and color Doppler ultrasound assessment of eyes in healthy dogs
Pesquisa Veterinária Brasileira: B-scan ultrasonography is an important diagnostic tool that allows characterization of internal organ anatomy and, when complemented by Doppler ultrasound, allows vascular hemodynamic assessment, increasing the diagnostic accuracy. Thus, the aim of the

Ultrasonic Doppler measurement of renal artery blood flow [PDF]
Studies were made of (1) blood flow redistribution during lower body negative pressure (LBNP), (2) the profile of blood flow across the mitral annulus of the heart (both perpendicular and parallel to the commissures), (3) testing and evaluation of a ...

Prediction of Severity of Coronary Stenosis in the Absence of Infarction by Tissue Doppler Imaging and Conventional Echocardiography at Rest [PDF]
Journal of Cardiovascular and Thoracic Research, 2011 Tissue Doppler imaging (TDI) is a relatively new method that measures regional myocardial velocities on the basis of color Doppler imaging. The aim of this study was to investigate both systolic and diastolic parameters to diagnose coronary stenosis at ...

Pure single photons from a trapped atom source
, 2016 Single atoms or atom-like emitters are the purest source of on-demand single photons, they are intrinsically incapable of multi-photon emission. To demonstrate this degree of purity we have realized a tunable, on-demand source of single photons using a ...

In Vitro Flow Modelling for Mitral Valve Leakage Quantification [PDF]
, 2009 In this study particle image velocimetry (PIV) is used to measure and visualise the blood flow through a leaking mitral heart valve. The results are compared with the results from Doppler echocardiography and computational fluid dynamics (CFD). Using CAD,
