【Abstract】 Monte Carlo method is used to simulate light distribution in human lung that is irradiated respectively by two different surface sources,i.e.,a Guassian beam and a flat beam.The fluence rate and the diffuse reflectance distribution of the tissue are simulated when the two different surface sources with different beam sizes illuminate the tissue respectively.It is shown that the choices of the beam shape and size will affect laser′s applications in clinic.更多还原
