Results of LSQ (blue) and DP (red) methods using approach 1 in a simulated phantom with three layers and 20 instances of added zero-mean Gaussian noise. The error bars show the standard deviation over the 20 instances of noise for attenuation coefficient (a), backscatter coefficient magnitude B (b), ESS a (c), and acoustic concentration (d). The black dashed line is the known values.
