AbstractTwo-dimensional (2-D) myocardial elastography is a frequency (RF)-based speckle tracking technique that uses dimensional (1-D) cross-correlation and recorrelation in a 2-D search, and can estimate and image the 2-D motion and deformation of the myocardium so as to the cardiac function. Based on a three-dimensional (3-D) finite-element (FE) canine left-ventricular model, a framework was previously developed by our group to the estimation quality of 2-D myocardial elastography a linear array. In this paper, an ultrasound simulation , Field II, was used to generate the RF signals of a model the heart in a phased array configuration and under 3-D condition; simulating thus the standard exams. The estimation method of 2-D elastography was adapted for use with such a . All elastographic displacements and strains were to be in good agreement with the FE solutions, as indicated the mean absolute errors (MAE's) between both. The results different sonographic signal-to-noise ratios (SNRs) showed that MAE's of the axial, lateral, radial and circumferential strains relatively unaffected, when the SNRs was higher than dB. The MAE's of the strain estimation were not significantly when the acoustic attenuation was included in the. The proposed framework can further be used to the quality, explore the theoretical limitation and the effects of various parameters in 2-D myocardial under more realistic conditions. ©2008 IEEE.
