Near-infrared diffuse optical tomography (DOT) technique has the capability of providing
good quantitative reconstruction of tissue absorption and scattering properties with
additional inputs such as input and output modulation depths and correction for the photon
leakage. We have calculated the two-dimensional (2D) input modulation depth from three-
dimensional (3D) diffusion to model the 2D diffusion of photons. The photon leakage when
light traverses from phantom to the fiber tip is estimated using a solid angle model. The …
