SNR_Hot computed from simulated measurements of light intensity (filled circles) and phase (open circles) in homogeneous background of optical properties vs. the depth of 1 cm³ spherical target contrasted from its surroundings by 10:1. The centroid of the target lies in the z-axis of breast geometry (Fig. 1). The target depth is measured as the distance from its centroid to the point (0, 0, 5) in breast geometry.
