A computational model for light transporting in biological tissues irradiated by converging laser beam

摘要

A semi-analytical method has been developed to calculate the spatially resolved diffuse light in layered biological tissues irradiated by converging laser beam based on the diffusion theory. Monte Carlo method is used to evaluate the correctness of the method, results show that they have good consistency and our method has higher computational efficiency. Numerical calculations disclosure same important features that are uniquely related to the propagation of the converging light in biological tissues. Those features are valuable to optimize the optical diagnosis and therapy.
