Experimental analysis shows improved moduli estimation in soft tissue using Rayleigh wave phase velocity, indicating method reliability.

Reconstruction methods using Rayleigh wave phase velocities show accurate estimations of elastic moduli in soft tissues.
Point-like and line source wave excitations yield similar results when analyzing the angular anisotropy of Rayleigh waves.
Using group velocity for moduli inversion leads to inadequate predictions, highlighting a need for better approaches.
The line source method is optimal for scanning surfaces, while the point-like source is better for single-point estimations.

Regnault et al. (2025) studied this question.
