Abstract
Systems and methods for attenuation measuring using ultrasound. In various embodiments, echo data corresponding to a detection of echoes of one or more ultrasound signals transmitted into tissue are received. The echoes can be received from a range of depths of the tissue. Spectral measurements across the range of depths of the tissue are obtained using the echo data. Attenuation characteristics of the tissue across the range of depths of the tissue can be estimated using the spectral measurements across the range of depths of the tissue. Specifically, the attenuation characteristics of the tissue can be estimated using the spectral measurements and known spectral characteristics of the one or more ultrasound signals transmitted into the tissue.

A method for estimating attenuation characteristics of a tissue using ultrasound comprising:
- receiving echo data corresponding to a detection of echoes of one or more ultrasound signals transmitted into the tissue, wherein the echoes are received from a range of depths of the tissue;
- obtaining spectral measurements across the range of depths of the tissue using the echo data;
- estimating attenuation characteristics of the tissue across the range of depths of the tissue using the spectral measurements across the range of depths of the tissue and known spectral characteristics of the one or more ultrasound signals transmitted into the tissue;
- filtering the echo data generated by the one or more ultrasound signals based on a depth of the one or more ultrasound signals in the tissue where the corresponding echo data is created;
- and
- obtaining the spectral measurements across, at least part of, the range of depths of the tissue using the filtered echo data.
