Fig. 2From: Regional myocardial strain analysis via 2D speckle tracking echocardiography: validation with sonomicrometry and correlation with regional blood flow in the presence of graded coronary stenoses and dobutamine stressa) Raw sonomicrometer displacement and hemodynamic curves for a given acquisition. Each acquisition generated 462 displacement curves to account for each pair combination of the 22 crystals. b) Video [image] of cycle-dependent crystal positions as determined by 3D crystal coordinate solutions of the displacement curvesBack to article page
