Speckle tracking echocardiography in cardiac amyloidosis
Heart Failure Reviews, 2019Speckle tracking echocardiography is an imaging method, based on analysis of 2D echocardiographic images, that is useful in providing information on tissue deformation in different cardiac diseases. Cardiac amyloidosis is a complex pathological entity that can be confused with other causes responsible for cardiac hypertrophy, and for this reason, it ...

Lateral speckle tracking using synthetic lateral phase
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004In traditional speckle tracking, lateral displacement (perpendicular to the beam direction) estimates are much less accurate than axial ones (along the beam direction). The accuracy of lateral tracking is very important whenever spatial derivatives of both axial and lateral displacements are required to give a full description of a two-dimensional (2-D)

[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 ...

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 ...

Two dimensional speckle tracking echocardiography: clinical applications
Heart, 2010This review is the second of two articles that focus on two dimensional speckle tracking echocardiography (STE). While the first article described the principles of STE, this review deals with its potential clinical applications. The technology of speckle tracking based strain analysis is rather new.w1 w2 However, there is considerable experience with ...

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.

Principles of speckle tracking
2018A vast amount of speckle tracking techniques has been developed to extract tissue motion from a time series of medical US images. The purpose of this chapter is to explore the underlying principles of these techniques while highlighting the methodological variety.
