The polynomial fit $\left(\alpha =\text{a}\mathit{f}+\text{b}{\mathit{f}}^2\right)$ of the attenuation of the two batches of TMM measured by Vevo 770 scanner and the SAM system

Transducer	710B	707B	704	711	Combination	SAM
Batch 1	0.47f + 0.00090f2	0.40f + 0.0074f2	0.43f + 0.0048f2	0.45f + 0.0055f2	0.39f + 0.0069f2	0.32f + 0.011f2
Batch 2	0.53f + 0.00030f2	0.50f + 0.0048f2	0.46f + 0.0059f2	0.48f + 0.0069f2	0.39f + 0.0088f2

TMM = tissue mimicking material; SAM = scanning acoustic macroscope.
