In this paper, two-dimensional angle-independent myocardial elastography (2DME) was employed in order to assess and image myocardial deformation (or, strains) in an entire left-ventricular view and was further validated against tagged magnetic resonance imaging (tMRI) in normal as well as abnormal human subjects. Both RF ultrasound and tMRI frames were acquired in a 2D short-axis (SA) view at the...
In this paper, myocardial elastography (ME), a radio-frequency (RF) based speckle tracking technique, was employed in order to assess the contractility of a myocardium, and validated against tagged magnetic resonance imaging (tMRI) in vivo in normal as well as abnormal cases. Both RF ultrasound and tMRI frames were acquired in 2D short-axis (SA) views from two healthy subjects and one with a history...
Myocardial elastography (ME), a radio frequency (RF)-based speckle tracking technique with one-dimensional (1-D) cross correlation and novel recorrelation methods in a 2-D search was proposed to estimate and fully image 2-1) transmural deformation field and to detect abnormal cardiac function. A theoretical framework was first developed in order to evaluate the performance of 2-D myocardial elastography...
