(Color online) Estimates obtained from 25 ROIs using the Gaussian and the 3DZM-deduced FF. (a) Each ROI was filled with a random number of randomly located Gaussian scatterers. Each ROI contained scatterers of diameter 32 μm. (b) Each ROI was filled with a random number of randomly located Gaussian scatterers. Each ROI contained scatterers following a Gaussian size distribution with mean diameter of 32 μm and standard deviation of 8 μm.
