2022 article
in vivo VisR Measurements of Viscoelasticity and Viscoelastic Anisotropy in Human Allografted Kidneys Differentiate Interstitial Fibrosis and Graft Rejection
2022 IEEE INTERNATIONAL ULTRASONICS SYMPOSIUM (IEEE IUS).
author keywords: ARFI; Elastography; VisR; Beamforming; Anisotropy; Viscoelasticity; Fibrosis; Inflammation
TL;DR:
Viscoelastic Response imaging is relevant to early detection of transplant kidney fibrosis and rejection, which could enable timely interventions that extend graft life, and noninvasive VisR RE-based RR had similar performance but also differentiated rejected from fibrotic kidney.

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.
