Normalized histograms of combined sphere size measurements for the nominally sized (top), (middle), and (bottom) phantoms as a function of sphere diameter.
Attenuation coefficient results for the 90–125, 125–150, and phantoms. The attenuation coefficients measurements were conducted at each laboratory using standard insertion loss techniques (Anderson et al., 2010) wherein at UIUC a broadband technique was used and at UW a narrow band technique was used.
BSC results for the (top), (middle), and (bottom) phantoms. The BSC theory curves used the measured combined sphere diameter distributions with the three BSC theories.
Compositions of spheres and background material.
Means and standard deviations of agar spheres that were measured at UW and UIUC, as well as the combined results. Note that the sizing method was different for each group.
Transducer information for UIUC and UW BSC measurements.
