Does COMSOL have the same capabilities as the monte carlo method in modeling light-tissue interactions in terms of calculating and obtaining light distribution over the surface as well as inside the tissue in 3D?
Thank you.
Hi,
Some research as: Assessing the spatial extent of breast tumor intrinsic opticalcontrast using ultrasound and diffuse optical spectroscopy Ang Li, Jing Liu, Wendy Tanamai, Richard Kwong, Albert E. Cerussi, and Bruce J.Tromberg, and other on the attached links reports the use of COMSOL trying to solve by FEM the model.
Please check the options and I hope you can find some tips.
Best wishes

Hi,
Comsol cannot offer you the same accuracy as MC. The reason is obvious: Comsol can solve the diffuse approximation (DA) equation, which is valid only in high scattering media and far enough from the source. On the contrary, MC can provide results more or less equal to the radiation equation if enough photons are used.
Some more links for Comsol and DA:

Best regards
Actually I am doing this right now. And I confront some problems. Dr. Milanic is right, Comsol solves the DA equation, and the result is not as accurate as MC. The following is the link of a short tutorial of COMSOL, which helps a lot. We can discuss it when you done your work.
