Journal ArticleDOI
Time-varying autoregressive spectral estimation for ultrasound attenuation in tissue characterization
TL;DR: The preliminary results obtained with the proposed time-variant methods, compared with the classical short-time Fourier analysis and the short- time auto-regressive (AR) analysis, are superior in terms of standard deviation of the attenuation coefficient estimate.
Journal ArticleDOI
High Frequency Ultrasound Device to Investigate the Acoustic Properties of Whole Blood During Coagulation
TL;DR: Results obtained showed that simultaneous measurements of parameters in DT and BS modes are able to identify several stages during the in vitro blood clotting process, in particular, red blood cell (RBC) aggregation can be described from the backscattering parameters and liquid-gel transition phase of blood from the sound velocity.
Journal ArticleDOI
Skin anisotropy in vivo and initial natural stress effect: a quantitative study using high-frequency static elastography.
TL;DR: A battery of elastographic tests were carried out to investigate forearm skin anisotropy quantitatively by measuring local through-thickness strain in the dermis by means of high frequency elastography and showed the effectiveness of elASTographic tests to describe and quantify the anisotropic behavior of the forearm skin in vivo.
Journal ArticleDOI
High-frequency estimation of the ultrasonic attenuation coefficient slope obtained in human skin: simulation and in vivo results
TL;DR: This acoustic parameter shows the effect of the ageing process on normal skin tissue in vivo by estimating the slope of the attenuation coefficient in the human dermis.
Journal ArticleDOI

TL;DR: In vivo studies are needed to demonstrate a better efficacy and safety of STL compared to currently approved therapeutic options, and several studies demonstrated superiority of STL versus recombinant tissue-type plasminogen activator on clinical criteria.
