We describe a novel Monte Carlo code for photon migration through 3D media with spatially varying optical properties. The code is validated against analytic solutions of the photon diffusion equation for semi-infinite homogeneous media. The code is also cross-validated for photon migration through a slab with an absorbing heterogeneity. A demonstration of the utility of the code is provided by showing time-resolved photon migration through a human head. This code, known as 'tMCimg', is available on the web and can serve as a resource for solving the forward problem for complex 3D structural data obtained by MRI or CT.
我们描述了一种用于光子在具有空间变化光学特性的三维介质中迁移的新型蒙特卡罗代码。该代码针对半无限均匀介质的光子扩散方程的解析解进行了验证。该代码还通过光子在具有吸收性不均匀性的平板中的迁移进行了交叉验证。通过展示时间分辨的光子在人头部的迁移，证明了该代码的实用性。这个名为“tMCimg”的代码可在网上获取，可作为求解通过MRI或CT获得的复杂三维结构数据的正向问题的资源。
