The software on Monte Carlo simulation of light transport in 3-D voxelized media is released (called MCVM). By using MCVM, researchers can obtain both steady-state and time-resolved light transport properties in biological tissue with realistic shape and structure. MCVM is fully documented, including its article and instructions. we also provide its application examples on visible Chinese human and digital rat. The source code of MCVM is open. Anyone can download this software in free but please cite our article: Ting Li, Hui Gong,Qingming Luo, MCVM: Monte Carlo modeling of photon migration in voxelized media, Journal of Innovative Optical Health Sciences, 3(2): 91-102, 2010.
