Histograms of scatterer size estimates from different blocks, computed for data from the test phantom using the VFX9-4 transducer. Any estimate that resulted in an imaginary value is assigned to be 5 μm. Panel (a)–(c) are estimated using a 5 wavelength window and averaged over 3 independent A-lines using (a) a Hanning window, (b) the Welch method, and (c) a rectangular a window. Panel (d) was obtained using an 11 wavelength window and averaged over 9 independent A-lines using the Welch method.
