Assessing the Impact of ARF Excitation Beam Width and Tracking Beam Concurrency on DoPIo Imaging Performance in a Calibrated Phantom
INTERNATIONAL ULTRASONICS SYMPOSIUM (IEEE IUS 2021).
author keywords: ARFI; Elastography; DoPIo; Speckle Tracking; PSF; Beamforming; Displacement Underestimation
TL;DR:
In silico experiments suggested that DoPIo acquisitions performed using a wide ARF push beam and simultaneous tracking provided the most accurate and precise elasticity estimates, while all four combinations of parameters enabled the differentiation of a soft inclusion within a stiff background in vitro.
