Background: The simulated Doppler blood flow signals are widely used to assess the
performance of the clutter filters for removing wall components while reserving low-velocity …

A computer simulation model based on an analytic flow velocity distribution is proposed to
generate Doppler ultrasound signals from pulsatile blood flow in the vessels with various …

In this study, a method has been proposed to model doppler ultrasound signals from blood
flow passing through stenosed vessels using simulation of RF signals obtained from …

The Doppler ultrasound technique is used to detect vascular stenosis as a non-invasive
procedure. To look for characteristics of Doppler ultrasound signals that are susceptible to …

Doppler ultrasound is a usual non-invasive method to estimate the stenosis percentage in
large arteries such as carotid by measuring maximum velocity of blood flow. Based on …

Objective: Duplex ultrasound scanning with B-mode imaging and both color Doppler and
Doppler spectral waveforms is relied upon for diagnosis of vascular pathology and selection …

A novel computer simulator to generate mixed Doppler ultrasound signals from the pulsatile
blood flow and vessel wall with mild stenosis is presented in this paper. In-phase and …

Understanding the spatiotemporal change in hemodynamics is essential for the basic
research of atherosclerosis. The objective of this study was to establish a methodology to …

Purpose Doppler-based methods are widely used for blood flow imaging in clinical settings.
However, they inherently estimate the velocity component only in the axial direction …

The study presented in this paper is concerned with the analysis of the ultrasound Doppler
signal of the carotid arteries in the time-frequency domain using the short time Fourier …
