摘要：

An approximate method that solves the 3D diffusion equation in geometries of arbitrary shape and size in a linear fashion is presented. The approximation has been compared to the ET solution of the diffusion equation. It was been found that when the average radius of the geometry considered is R>3(D/μa)1/2, the method performs with an error less than 5%.
