Pulse wave and color flow Doppler imaging were also used to screen senescent mice for valve abnormalities; AI was detected in 3 of 20 and mitral regurgitation in 2 of 20. We demonstrate here that PW and color flow Doppler imaging techniques are useful in the evaluation of mouse models of ...
Pulse transit times between the two Doppler signals were measured by cross-correlating the signals and the aPWV was calculated, knowing the distance between the probes (measured to the nearest millimetre with a flexible tape). There was good correlation between the pulse wave ve...
Transcranial Doppler studies have in the past relied on the use of static 2.0-MHz pulsed wave Doppler to obtain Doppler spectra "blindly" from the intracranial vasculature. Thirty patients were evaluated with both static 2.0-MHz pulsed w... KA Fujioka,DT Gates,MP Spencer - 《Journal of Vascula...

Pulse wave velocity (PWV) measurement is widely used for the indirect assessment of arterial wall distensibility. In order to improve its measurement technique, we built a system performing the calculation of the cross-correlation function of Doppler velocity signals. In 12 normal subjects and 10 pa...
Fig. 1. Overview of data processing steps used to obtain the pulse wave velocity (PWV) value from the original arterial displacement curves. Statistical analysis A statistical analysis was performed on the obtained average pulse wave velocities with FFI and PWI. The distribution of continuous variabl...
Increased arterial stiffness is observed in a number of cases. The analysis of the regional functional arterial properties is of interest to determine the role of a given risk factor on the vascular wall and in some diseases such as atherosclerosis. We a
Pulse modulation refers to a type of modulation where a parameter of a pulse train is varied in accordance with the message, as opposed to continuously varying a parameter of a sinusoidal carrier wave in continuous wave (CW) modulation.
