Reply to 'Comments on "The effect of logarithmic compression on the estimation of the Nakagami parameter for ultrasonic tissue characterization"'

This letter clearly explains the logarithmic technique used to enhance the sensitivity of the Nakagami parameter in quantifying the properties of biological tissues. That is, the ultrasonic backscattered envelopes were firstly added to 1 and subsequently compressed by the logarithmic transform. The compressed envelopes can be treated as Nakagami-distributed data and can be directly utilized to estimate the Nakagami parameter from second and fourth moments of compressed envelopes, denoted by m_log. The m_log parameter is more sensitive than the original Nakagami parameter estimated using uncompressed envelopes in differentiating various scatterer concentrations in a tissue. This may be more useful in tissue characterization based on the Nakagami statistical model.
