The percent standard deviation of the scatterer size estimates using (a) 5 μm assignment of imaginary values and (b) NaN assignment of imaginary value at 7cm (focus) depth and 11-wavelength window length vs. the number of independent A-lines averaged. The VFX9-4 transducer data were used for the curves. The theoretical values are calculated according to equation (5) assuming a rectangular window and equation (6).
