摘要

Monte Carlo simulation plays an important role in the photon propagation in the biological tissue. The selection of photon quantity in Monte Carlo simulation is significant since it affects accuracy, reliability and time cost. It deduced an empirical formula confirm photon quantity to avoid concave phenomenon appeared at the center of the transmission plane. And the formula was concluded through the relationship between the simulation accuracy, geometry parameters of tissue, optical parameters of medium and the photon number. The result is shown by testing several simulations with different optical parameters, and it not only can improve the accuracy of simulation, but also reduce simulation time according to the requirements of the required accuracy. This study provides a reference for determining appropriate photon quantity in simulation, and ideas for other optical analysis of MC simulation.
