Abstract
Monte Carlo (MC) method is widely used in the research of photon migration in biological tissues because of its good flexibility and high accuracy. In this paper, we investigated the principle of excitation photon migration in the first type of the Fluorescence Molecular Tomography (FMT) system. By setting up MC model and simulation, we figured out the relationship between the received photon intensity of each detector and the radius of the homogeneous cylinder media in the system. The simulation result showed good spatial symmetry of the received intensity of each detector with the excitation light. The received intensity was proved to decrease exponentially with the radius of the cylinder media.
