Baseline chromophore concentration values from DOS measurements in the three rabbit models. The water fraction is the water concentration in tissue relative to the concentration of pure water (55.6 M) and the lipid fraction is the lipid mass density () in tissue relative to a lipid mass density of . DeOxyHb, OxyHb, and THb represent deoxyhemoglobin, oxyhemoglobin, and total hemoglobin (), respectively. Parameters associated with the power-law fit of five discrete frequency domain reduced scattering coefficients at baseline, prefactor (), and scattering power (SP) where , from three rabbit models are also listed. Data are presented as (standard error of mean). Numbers of animals in control, CN (10 mg), and hemorrhage are 5, 5, and 4, respectively.
