[Speckle tracking echocardiography: a practical guide].
Giornale italiano di cardiologia (2006), 2017Speckle tracking echocardiography (STE) has recently emerged as a quantitative technique to accurately estimate myocardial function. By the analysis of the motion of speckles in the two-dimensional ultrasonic image, this technique allows a non-Doppler angle-independent objective analysis of myocardial deformation, with the possibility to quantify ...

A fast method for speckle tracking
2012 IEEE International Ultrasonics Symposium, 2012Speckle tracking method has been studied for velocity vector imaging in medical ultrasound for many years. However, the method is slow as compared to the conventional color Doppler imaging due to a larger amount of computation is needed. In this study, a method is developed to reduce the amount of computation.

Three-dimensional speckle tracking
Current Cardiovascular Imaging Reports, 2008Two-dimensional speckle tracking is a useful technology. Nevertheless, it has some limitations because the heart has three dimensions. The recent development of three-dimensional speckle tracking technology provides a new diagnostic tool. By using this new method, a more complete and probably accurate evaluation of global and segmental left ventricular

Techniques for speckle tracking: block matching
2018The clinical need for in vivo motion and deformation quantification and the many applications have been clearly explained in the previous chapters. In general, we distinguish between (1) quasi-static elastography: speckle tracking during compression or palpation of tissue to estimate local strains and elasticity and (2) dynamic elastography, where ...

Speckle tracking echocardiography: imaging insights into the aorta
Current Opinion in Cardiology, 2020Purpose of review Pathophysiologic changes of aortic tissue may not always manifest as aneurysms, nor does the size of an aneurysm necessarily represent the severity of tissue abnormality – approximately 40% of patients who present with dissection have aortic diameters below criteria recommended for surgical resection ...

Speckle Tracking in the Evaluation of Left Ventricular Dyssynchrony
Echocardiography, 2009A number of echocardiographic techniques have been introduced to determine left ventricular dyssynchrony (LVD) and to improve selection of patients for CRT. During the last years tissue Doppler imaging (TDI) has been used as the most preferred technique to quantify LVD, but results with nonresponder rates below 30% have been shown only in small ...

Speckle tracking for multi-dimensional flow estimation
Ultrasonics, 2000Speckle tracking methods overcome the major limitations of current Doppler methods for flow imaging and quantification: angle dependence and aliasing. In this paper, we review the development of speckle tracking, with particular attention to the advantages and limitations of two-dimensional algorithms that use a single transducer aperture.

Speckle tracking technology for quantifying lung sliding
Medical Hypotheses, 2016Ultrasound (US) is gaining recognition as a useful tool for assessing lung physiology and pathology. Yet, currently the skill of performing lung US is taught by experienced operators to novice ones, mainly by recognizing expected patterns. Recognizing the latter may be difficult and subjective.
