Figure 3
Comparison of phase maps obtained from the TMA-1 before and after staining. (a,b) TMA core raw phase images before and after staining, respectively. (c) Histograms of the phase images in (a,b). The similarity of the two histograms is quantified by computing the Pearson’s correlation coefficient ρ between them. (d) and (e) Normalized maps for the same core before and after staining, respectively. (f) Histograms of the images in (d,e). The similarity of the two histograms is quantified by computing the Pearson’s correlation coefficient ρ between them. (g) Bar plots showing the mean value of Pearson’s correlation coefficient ρ between core histograms for raw and normalized phase maps. Error bars show the standard deviation over the 30 cores.
