Richardson J, Moore C, Gallippi C
IEEE Trans Ultrason Ferroelectr Freq Control . 2024 May; 71(7):910-923. PMID: 38781057
We present a machine learning method to directly estimate viscoelastic moduli from displacement time-series profiles generated by viscoelastic response (VisR) ultrasound excitations. VisR uses two colocalized acoustic radiation force (ARF)...

Anand K, Torres G, Homeister J, Caughey M, Gallippi C
IEEE Trans Ultrason Ferroelectr Freq Control . 2023 May; 70(7):636-652. PMID: 37216241
A significant risk factor for ischemic stroke is carotid atherosclerotic plaque that is susceptible to rupture, with rupture potential conveyed by plaque morphology. Human carotid plaque composition and structure have...

Czernuszewicz T, Aji A, Moore C, Montgomery S, Velasco B, Torres G, et al.
Hepatol Commun . 2022 Feb; 6(7):1827-1839. PMID: 35202510
Shear wave elastography (SWE) is an ultrasound-based stiffness quantification technology that is used for noninvasive liver fibrosis assessment. However, despite widescale clinical adoption, SWE is largely unused by preclinical researchers...

Hossain M, Gallippi C
IEEE Trans Med Imaging . 2022 Jan; 41(6):1468-1481. PMID: 34995184
Elastic degree of anisotropy (DoA) is a diagnostically relevant biomarker in muscle, kidney, breast, and other organs. Previously, elastic DoA was qualitatively assessed as the ratio of peak displacements (PD)...

Wu H, Hossain M, Kim H, Gallippi C, Jiang X
IEEE Trans Ultrason Ferroelectr Freq Control . 2020 Oct; 68(4):1278-1287. PMID: 33044921
Many biological tissues, including muscle or kidney, are mechanically anisotropic, and the degree of anisotropy (DoA) in mechanical properties is diagnostically relevant. DoA can be assessed either using the ratio...

Hossain M, Gallippi C
IEEE Trans Ultrason Ferroelectr Freq Control . 2020 Aug; 68(3):632-646. PMID: 32833634
Degree of anisotropy (DoA) of mechanical properties has been assessed as the ratio of acoustic radiation force impulse (ARFI)-induced peak displacements (PDs) achieved using spatially asymmetric point spread functions (PSFs)...

Torres G, Czernuszewicz T, Homeister J, Farber M, Caughey M, Gallippi C
IEEE Trans Med Imaging . 2020 Aug; 39(12):4383-4390. PMID: 32833633
This study evaluates the performance of an acoustic radiation force impulse (ARFI)-based outcome parameter, the decadic logarithm of the variance of acceleration, or log(VoA), for measuring carotid fibrous cap thickness....

Hossain M, Gallippi C
IEEE Trans Ultrason Ferroelectr Freq Control . 2020 Jan; 67(6):1102-1117. PMID: 31899421
Viscoelastic response (VisR) ultrasound characterizes the viscoelastic properties of tissue by fitting acoustic radiation force (ARF)-induced displacements in the region of ARF excitation to a 1-D mass-spring-damper (MSD) model. Elasticity...

IEEE Trans Ultrason Ferroelectr Freq Control . 2019 Feb; 66(3):481-492. PMID: 30762544
While in vivo acoustic radiation force impulse (ARFI)-induced peak displacement (PD) has been demonstrated to have high sensitivity and specificity for differentiating soft from stiff plaque components in patients with...

Selzo M, Moore C, Hossain M, Palmeri M, Gallippi C
IEEE Trans Ultrason Ferroelectr Freq Control . 2018 Dec; 66(1):251. PMID: 30507501
In the original publication of this paper [1], equation (3) contained sign errors for the amplitude of the third and fourth Heaviside functions. The corrected equation is shown in the...
