SNR_Hot computed from simulated measurements of light intensity (filled circles) and phase (open circles) as a function of strength of lumps in (a) the endogenous optical properties (μ_axi, μ_ami, μ_sx, and μ_sm), and (b) endogenous as well as exogenous (μ_axf, and μ_amf) optical properties vs. the strength of lumps. The target is a 1 cm³ spherical volume at a depth of 1 cm and contrasted from its surroundings by 10:1. The centroid of the target is at (0, 0, 4) inside the breast geometry (Fig. 1).
