Simulation of the effect of purulent content of the maxillary sinuses on the transillumination signal

In this paper the optical properties of the purulent content of the maxillary sinuses were obtained by spectrophotometry. Based on the obtained absorption and reduced scattering coefficients, a numerical simulation by Monte Carlo method was performed to determine the pattern of light scattering passing through the maxillary sinus with purulent contents. The results of the simulation showed that in transillumination methods for the detection of purulent pathological changes, it is more informative to use the radiation sources with 980 nm.
