Effects of background scattering properties on fit parameters. Filled circle represents the predicted fit parameters for an inclusion at the specified depth and thickness in (left) our phantom model (μ_a = 0.2 mm⁻¹, μ_s = 4.0 mm⁻¹, and g = 0.8) and (right) in our skin-like model (μ_a = 0.2 mm⁻¹, μ_s = 45 mm⁻¹ (100 micron thick epidermis) and μ_s = 30 mm⁻¹ (dermis) and g = 0.8). The colored triangles represent fit results when the background scattering coefficient is increased by 10% (upward pointing triangles) or decreased by 10% (downward pointing triangles). While the absolute prediction for each location changes somewhat, the trends related to relative depth and thickness are retained.
