Calibration of ARFI displacements using diastolic shear wave speeds for estimating systolic elasticity


Conference Paper

© 2017 IEEE. ARFI displacements have been shown to share an inverse relationship with shear wave speed - based estimates of tissue elasticity. In transthoracic imaging, induced shear waves have been observed during diastole, but only ARFI displacements have been accurately measured through both diastole and systole. We propose here a method for using diastolic shear wave speeds to calibrate ARFI displacement magnitudes, allowing ARFI displacements to be independently used to quantify shear wave speed throughout the cardiac cycle.
