Ma J et al study based on nondiabetic subjects, suggest that an automated oscillometric ABI measurement is a reliable and practical alternative to the conventional doppler measurement
for the detection of PAD,11 but our objective of the study was to involve diabetic patients to validate automated oscillometric ABI method.
Various echo tools for diastolic assessment are M-mode measurement, 2D echo measurement, Doppler measurement-transmitral Doppler measurement
, pulmonary venous flow measurement, colour M mode, tissue Doppler imaging methods.
The Relationship Between Uterine Artery two-dimensional Color Doppler Measurement
and Pregnancy Outcome: A Prospective Observational Study.
Then, E/E' ratio was calculated to provide an estimation of LV filling pressures.[sup] The myocardial performance index (MPI), which is a noninvasive Doppler measurement
of global ventricular function, was calculated as the ratio of isovolumic contraction and relaxation times to ejection time.
The strength of this study is that it is the first regional study to demonstrate the successful application of non-invasive method of fetal MCAPSV Doppler measurement
to diagnose fetal anemia in various scenarios, although few case reports have been reported earlier.
of the middle cerebral artery (MCA) was performed for the prediction of fetal anemia and the peak systolic velocity (PSV) was significantly elevated (60 cm [s.sup.-1]).
There was ventricular septal flattening consistent with right ventricular pressure overload, and pulmonary arterial systolic pressure, estimated from Doppler measurement
of tricuspid regurgitant jet velocity and a dilated inferior vena cava, was ~ 80 mmHg.
Simultaneous Doppler measurement
of portalvenous peak velocity, hepatic arterial peak velocity, and splenic arterial pulsatility inex for assessment of hepatic circulation.
of Sydney) explains the fundamentals of signal processing and modulation before moving on to IR radiometers and image intensifiers, millimeter wave radiometers, active ranging sensors, active imaging sensors, signal propagation, Doppler measurement
and radio frequency ID tags and transponders.
For products flowing through a pipe, researchers have developed a viscosity meter based on ultrasonic Doppler measurements
. The lab's ultrasonic Doppler measurement
system can be used to build a velocity profile for product flowing through a pipe, which can be an invaluable tool for process engineers.
"The Doppler measurement
is a lot like listening to a train whistle," Pappas says.
