Correlation-based full-waveform shear wave elastography

PHYSICS IN MEDICINE AND BIOLOGY, 68(11).

By: A. Elmeliegy n  & M. Guddati n 

Contributors: A. Elmeliegy n  & M. Guddati n

MeSH headings : Elasticity Imaging Techniques / methods; Phantoms, Imaging; Ultrasonography; Elasticity; Physics
TL;DR: A methodology of inverting for 2D elasticity maps from measurements on a single line is presented that has better convexity and convergence properties compared to the traditional least-squares functional, and is less sensitive to initial guess, robust against noisy measurements and other errors that are common in ultrasound elastography.

Shear wave elastography: From dispersion matching to full waveform inversion

Guddati, M., Roy, T., Elmeliegy, A. M., & Urban, M. W. (2023, March). JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA, Vol. 153.

By: M. Guddati n , T. Roy* , A. Elmeliegy n  & M. Urban *

TL;DR: This paper presents inversion approaches ranging from matching dispersion characteristics to matching full waveform responses and provides rationale for choosing the appropriate technique(s) depending on the problem at hand. (via Semantic Scholar)
