About 92.1 million Americans suffer from at least one type of cardiovascular disease.
Worldwide, cardiovascular diseases are the number one cause of death (about 31% of all …

Commercial ultrasound systems can make a number of measurements related to
haemodynamics which are relevant to clinical practice and to clinical research. These …

A thermal model was needed to predict temperatures in a perfused tissue, which satisfied
the following three criteria. One, the model satisfied conservation of energy. Two, the heat …

The objective of this paper is to validate angle independent vector velocity methods for
blood velocity estimation. Conventional Doppler ultrasound (US) only estimates the blood …

Visualization of, and measurements related to, haemodynamic phenomena in arteries may
be made using ultrasound systems. Most ultrasound technology relies on simple …

In clinical practice, blood volume flow (BVF) is typically calculated assuming a perfect
parabolic and axisymmetric velocity distribution. This simple approach cannot account for …

To verify a previously reported three-dimensional (3D) ultrasound method for the
measurement of time-average volumetric blood flow, experiments were performed under …

Objectives: The aim of this study was to investigate whether early enhanced external counter
pulsation therapy after cardiopulmonary resuscitation improved neurological outcome in a …

Increase in flow rate within the azygos vein may be used as an indicator of the degree of
liver cirrhosis. The aim of this study was to evaluate the error in measurement of flow rate …

Objective. The purpose of this study was to compare peak systolic velocities (PSVs) and the
degree of stenosis obtained with a real‐time 3‐dimensional (ie, 4‐dimensional) Doppler …
