| Research Abstract |
We have obtained some new results as fundamental study for the diffused optical tomography (DOT), which is considered as a coming technology. The results are deduced through deep consideration, from both mathematics and computing, about mathematical models corresponding to DOT.In the project study, we focus on modeling errors which arise in mathematical modeling; we restrict ourselves to modeling errors in the transport equation model which is regarded as the fundamental mathematical one for propagation of photons in biomedical tissues. Through theoretical arguments and computings, we have pointed out some fatalmisunderstanding in the past studies for DOT based on mathematical analysis of the inverse problems.
