Attenuation Compensation and Estimation

Abstract

Estimating the loss of ultrasound signal with propagation depth as a function of frequency is essential for quantifying tissue properties. Specifically, ultrasound attenuation is used to correct for spectral distortion prior to estimating quantitative ultrasound parameters to assess the tissue. Ultrasound attenuation can also be used independently to characterize the tissue. In this chapter, we review the primary algorithms for estimating both the local attenuation within a region of interest as well as the total attenuation between a region of interest and an ultrasound source. The strengths and weaknesses of each algorithm are also discussed.

Keywords: Attenuation; Hybrid method; Local attenuation; Multiple filter method; Spectral difference method; Spectral-fit method; Spectral-log difference method; Total attenuation.
