TL;DR: An optimization method is proposed to simultaneously estimate tissue attenuation and blood structure properties, and was termed the structure factor size and attenuation estimator (SFSAE), which can be useful to examine in vivo and in situ abnormal blood conditions suspected to promote pathophysiological cardiovascular consequences.

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: A maximum a posteriori deconvolution framework expressly derived to improve tissue characterization is introduced and overcomes limitations associated with standard techniques by using a nonstandard prior model for the tissue response.

TL;DR: The total, coherent and diffuse signal powers related to the proposed mixture model are expressed explicitly in terms of the structure factor previously studied to describe the backscatter coefficient, illustrated in the context of red blood cell aggregation.

TL;DR: An experimental validation of the Structure Factor Size Estimator (SFSE), a non-Rayleigh scattering model adapted for dense suspensions, was performed on 4 erythrocyte preparations with different aggregation tendencies, finding that a "normal" aggregability promoted the formation of concentric rings with varying viscosities.
