Estimating the losses of ultrasound signal energy with propagation depth as a function of
frequency is essential for quantifying tissue properties. Specifically, ultrasound attenuation is …

Quantitative ultrasound (QUS) techniques are based on providing parameter estimates from
ultrasound backscattered signals that can be related to different properties of the tissue …

The acoustic attenuation coefficient of most soft biological tissues has an approximately
linear-with-frequency attenuation characteristic. The slope of the attenuation coefficient with …

Purpose: Quantitative ultrasound based approaches such as attenuation slope estimation
can be used to determine underlying tissue properties and eventually used as a …

Quantifying the size of the tissue microstructure using the backscattered power spectrum has
had limited success due to frequency-dependent attenuation along the propagation path …
