Abstract: Disclosed is a method for estimating ultrasound attenuation coefficient by use of aberration compensation and the reference phantom method. Measurements on a human sample at a single transmit frequency and on multiple reference phantoms at a plurality of transmit frequencies are performed respectively. The center frequencies of the echo signals at the depth of the top edge of the region of interest are calculated. A specific reference phantom at a specific transmit frequency is selected by the echo signals whose center frequencies are closest to the center frequencies of the echo signals from the human sample at the aforementioned depth to compensate for the aberration. Then the spectra of the echo signals from the selected reference phantom at the selected transmit frequency and the spectra from the echo signals from the human sample are used to estimate the attenuation coefficient of the human sample by following the reference phantom method.
