Background Flow properties play an important role in cardiac function, remodeling, and
morphogenesis but cannot be displayed in detail with today's echocardiographic …

High-frame-rate ultrasound speckle tracking was used for quantification of peak velocity in
shunt flows resulting from septal defects in congenital heart disease. In a duplex acquisition …

Realization of flow imaging at high frame rates is essential to the visualization of complex
flow patterns with fast-changing spatiotemporal dynamics. In this study, we present an …

The vector velocity method Transverse Oscillation (TO) implemented on a conventional
ultrasound (US) scanner (ProFocus, BK Medical, Herlev, Denmark) can provide real-time …

Conventional ultrasound (US) methods for blood velocity estimation only provide one-
dimensional and angle-dependent velocity estimates; thus, the complexity of cardiac flow …

Transverse oscillation (TO) is a real-time ultrasound vector flow method implemented on a
commercial scanner. The TO setup was examined on a flowrig with constant and pulsatile …

Secondary rotational flow and systolic backflow are seen in the ascending aorta and, in this
study, were analyzed with the vector velocity method transverse oscillation. Twenty-five …

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

Despite the availability of multiple ultrasound approaches to left ventricular (LV) flow
characterization in two dimensions, this technique remains in its childhood and further …

Objectives The aims of this study were to assess the vortex characteristics of left ventricle
(LV) in fetuses with coarctation of the aorta (CoA) using high–frame rate ultrasound with …
