The three-dimensional (3-D) Transverse Oscillation (TO) method is used to obtain 3-D
velocity vector estimates in two orthogonal planes. The method is suitable for a real-time …

We describe a new method, called ensemble tracking, for estimating two-dimensional
velocities with ultrasound. Compared to previous speckle tracking techniques, ensemble …

The pulse-wave velocity (PWV) is inversely related to arterial compliance, and provides a
useful measure of vascular function. In this study, the PWV was measured non-invasively in …

Atherosclerosis is characterized by local remodeling of arterial structure and distensibility.
Developing lesions either progress gradually to compromise tissue perfusion or rupture …

For more detailed measurement of cardiovascular motion and complex blood flow, a two-
dimensional (2D) velocity estimation method is required in functional ultrasound imaging …

The multi-angle Doppler method was introduced for the estimation of velocity vectors by
measuring axial velocities from multiple directions. We have recently reported that the …

The purpose of this study is to show whether a newly introduced vector flow method is equal
to conventional spectral estimation. Thirty-two common carotid arteries of 16 healthy …

It is very challenge to investigate the motion of the carotid artery wall in ultrasound images,
because of the high nonlinear dynamics of this motion. In our study, the nonlinear dynamics …

Transverse oscillation (TO) methods introduce oscillations in the pulse–echo field (PEF)
along the direction transverse to the ultrasound propagation direction. This may be exploited …
