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

Assessment Of Left Ventricular Systolic Function By Speckle Tracking Echocardiography In Young Hypertensive Patients [PDF]
Al-Azhar International Medical Journal, 2022 Background: Tissue Speckle Tracking examines speckle aberrations in an echo picture to determine myocardial contractility and relaxation. Reflections, refraction, and dispersion of echo beams generate speckles.
