Abstract

Biomedical optical imaging has a possibility of a comprehensive di- agnosis of thyroid cancer in conjunction with ultrasound imaging. For improvement of the optical imaging, this study develops a higher order scheme for solving the time-dependent radiative transport equa- tion (RTE) by use of the finite-difference and discrete-ordinate meth- ods. The accuracy and efficiency of the developed scheme are ex- amined by comparison with the analytical solutions of the RTE in homogeneous media. Then, the developed scheme is applied to de- scribing photon migration in the human neck model. The numerical simulations show complex behaviors of photon migration in the hu- man neck model due to multiple diffusive reflection near the trachea.
