TL;DR: Tissue-mimicking phantoms with high scatterer concentrations were examined using quantitative ultrasound techniques based on four scattering models based on the Gaussian model (GM), the Faran model (FM), the structure factor model (SFM), and the particle model (PM), finding the SFM was the model that better matched the BSC magnitude at all the scattere concentrations tested.

TL;DR: The data fitting quality and the scatterer size estimates show that the SFM was more suitable than the PM and the FFSM for modeling the responses from concentrated cell pellet biophantoms.

TL;DR: In this paper, the scattering of acoustic waves by an elastic sphere embedded in an elastic isotropic medium is investigated, and the resonances of the solid sphere were determined numerically in the individual normal mode amplitudes; dispersion curves for the phase velocities of the circumferential waves were also obtained.

TL;DR: Comparison between sparse and concentrated models shows that these hyperechogenic zones observed in the B-mode images were linked to the presence of small necrotic areas surrounded by viable HT29 cells and could be considered as a concentrated medium.

TL;DR: Acoustic signals generated in water by terawatt (TW) laser pulses undergoing filamentation are studied and such a source appears to be promising for the development of remote laser based acoustic applications.
