Abstract

Ultrasound attenuation coefficient estimation (“ACE”) techniques that can ameliorate frequency power ratio curve oscillations caused by signal interferences, non-uniform tissue structures, or both, are described. The resulting smoothed frequency power ratio curves enable more accurate ACE and reduced region-of-interest (“ROI”) sizes for linear regression.
