| Abstract(in English) | Numerical accuracy in finite difference time domain (FDTD) analysis in three-dimensional(3-D) optical scattering medium is described. Power of an isotropic point source located at 1/μ_s' below the surface is assigned to the Yee grid points at the both ends. When source power is assigned to a Yee grid point of k=1 in z ordinate, one fourth of the power is re-assigned to the surface grid point. 3-D homogeneous scattering medium was discretized into 0.5^3(mm^3) grids and backscattered power and time-resolve reflectance have been calculated by the FDTD analysis. The numerical results agree with the analytical solutions quite well, which justifies the FDTD analysis. Then, FDTD analysis to an adult head including non-scattering regions was applied, and the validity is verified. |
