Effects of anesthesia on conventional and speckle tracking echocardiographic parameters in a mouse model of pressure overload [PDF]

open access: yes, 2015
Genetically‑modified mice are widely applied in cardiovascular studies as model organisms. Echocardiography is a key tool for evaluating cardiac and hemodynamic functions in mice.

High-Frame-Rate Speckle-Tracking Echocardiography [PDF]

open access: yesIEEE 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.

Speckle tracking strain echocardiography: What sonographers need to know!

open access: yesJournal 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.

Speckle Tracking in Intracardiac Echocardiography for the Assessment of Myocardial Deformation [PDF]

open access: yesIEEE Transactions on Biomedical Engineering, 2009
Intracardiac echocardiography (ICE) has proven to be useful for online anatomical imaging during catheterization. Our objective was to develop a speckle tracking method for myocardial motion estimation from ICE image sequences in order to provide a mean for regional functional imaging.

Speckle tracking accuracy enhancement by temporal super-resolution of three-dimensional echocardiography images

open access: yesJournal of Medical Signals and Sensors, 2021
Background: Speckle tracking has always been a challenging issue in echocardiography images due to the lowcontrast and noisy nature of ultrasonic imaging modality. While in ultrasound imaging, framerate is limited by image size and sound speed in tissue,

FUSION OF TISSUE DOPPLER AND SPECKLE TRACKING IN ECHOCARDIOGRAPHY IMAGES: COMPARISON WITH SPECKLE TRACKING ECHOCARDIOGRAPHY

open access: yesJournal of the American College of Cardiology, 2013
Quantitative analysis of strain in cardiac imaging is crucial in treatment of cardiac disorders. Thus far, cardiac motion detection is based on tissue Doppler imaging (TDI) or speckle tracking echocardiography (STE).
