High-Frame-Rate Speckle-Tracking Echocardiography [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2018 Conventional echocardiography is the leading modality for noninvasive cardiac imaging. It has been recently illustrated that high-frame-rate echocardiography using diverging waves could improve cardiac assessment. The spatial resolution and contrast associated with this method are commonly improved by coherent compounding of steered beams.

Right ventricle speckle tracking in bronchopulmonary dysplasia: one-year follow-up
The Egyptian Heart Journal, 2023 Background Bronchopulmonary dysplasia (BPD) is still a major concern in preterm infants and adequate screening methods for secondary right ventricle (RV) failure are needed.

Speckle tracking strain echocardiography: What sonographers need to know!
Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017 Introduction: Strain is a unitless measurement of dimensional or deformational change; speckle-tracking echocardiography is the most widely used technique to assess strain, with demonstrated clinical utility in a variety of settings.

3D-based strain analysis and cardiotoxicity detection in cancer patients received chemotherapy
BMC Cancer, 2023 Background Chemotherapy-induced cardiotoxicity has become a prevalent complication. Regular monitoring of patients who received chemotherapy using 3D strain parameters may aid in early detection of myocardial damage and its prevention.

Continuous ultrasound speckle tracking with Gaussian mixtures [PDF]
2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015 Speckle tracking echocardiography (STE) is now widely used for measuring strain, deformations, and motion in cardiology. STE involves three successive steps: acquisition of individual frames, speckle detection, and image registration using speckles as landmarks.
