Validation of model extraction for absorption and scattering coefficient. Results from absorption (μa) and reduced scattering (μs’) variation study in experimental tissue phantoms. A) For absorption variation experiments, measurements of were taken from eight concentrations of Evans Blue dye (EB) in 1% Intralipid. The absorption coefficient was extracted using the proposed inversion algorithm. B) For scattering variation experiments, serial dilutions of Intralipid were measured at four volume fractions with no added absorber and reduced scattering coefficients were determined by our the algorithm. All optical properties are presented at 620 nm.
