(A) Plot of cost function for all tested acquisition parameters. Wavelength combinations are shown in the table on the top right. PA-based (B) S_fO₂ for a representative control mouse and (C) $\overline{{\text{S}}_{\text{f}}{\text{O}}_2}$ for control cohort. The average $\overline{{\text{S}}_{\text{f}}{\text{O}}_2}$ across the femoral extent for all time-points are summarized in the table on the bottom right.
