Fig. 3

Representative plot of the estimated BSCs pre-and post-treatment, along with their respective best-fit form factor from the SGM model. These are shown from two combination of treatment groups 246 kPa + 50 min (graph depicting plot of the estimated BSCs pre-and post-treatment 570 kPa + 50 min is shown in Supplementary Figure 2). The BSCs are estimated from 50 individual attenuation-corrected normalized power spectra from two-dimensional tumour ROI. An increase in the acoustic backscattering resulting from cell deaths 24-h post-treatment, relative to the pre-treatment, is apparent from the BSC plot
