Table 1. Summary of simulated optical parameters, including the average photon partial pathlengths in the brain region (${\mathrm{PPL}}_{\mathrm{B}}$), total-pathlengths (TPL), and their percentage ratios (${\mathrm{R}}_{\mathrm{B}}$) derived from SVMC simulation of B3 (“brain19.5”). We also include the ${\mathrm{R}}_{\mathrm{B}}$ reported by DMMC (reference) and MCX in [7].
