The authors summarize the recent developments in speckle-tracking echocardiography
(STE), a relatively new technique that can be used in conjunction with two-dimensional or …

Strain and strain rate (SR) are measures of deformation that are basic descriptors of both the
nature and the function of cardiac tissue. These properties may now be measured using …

Background—Mechanical dyssynchrony is a potential means to predict response to cardiac
resynchronization therapy (CRT). We hypothesized that novel echocardiographic image …

On the basis of color Doppler myocardial motion data, 1-dimensional regional natural strain
rate and strain curves can now be calculated by comparing local myocardial velocity …

Background—Strain and strain rate have been proposed as tools to quantify regional
myocardial function. One of the major pitfalls of the current methodology is its angle …

Purpose Echocardiography is a widely used modality for diagnosis of the heart. It enables
observation of the shape of the heart and estimation of global heart function based on B …

We propose a new spatio-temporal elastic registration algorithm for motion reconstruction
from a series of images. The specific application is to estimate displacement fields from two …

Background—Longitudinal myocardial deformation indexes appear superior to left
ventricular ejection fraction (LVEF) in assessing myocardial contractility. However, few …

Early detection of cardiovascular diseases has been a very active research area in the
medical imaging field. Assessment of the local and global mechanical functions is one of the …

Two-dimensional (2-D) strain (ε2-D) on the basis of speckle tracking is a new technique for
strain measurement. This study sought to validate ε2-D and tissue velocity imaging (TVI) …
