Properties derived from acoustic backscatter measurements are examined to disclose sources of acoustic scattering in normal kidneys. The backscatter intensity from kidney parenchyma may be modeled using a two-component Gaussian correlation function. These two components yield effective scatterer size estimates of 220 ± 15 μm at low frequencies and 55 ± 10 μm at high frequencies, which correspond to the average glomerular and renal tubule diameters, respectively. A separate study using test media verifies the ability of the method to distinguish between mixtures of two different scattering structures from backscatter measurements at different frequencies.
