Abstract :
We investigated the performances of time-gated dataset to perform functional DOT in a synthetic murine model. The light propagation model used was based on the Monte Carlo method for accuracy. It is found that time-gates provide superior performances compared to classical approaches. Especially, time gates allow for efficient separation between absorption and scattering heterogeneities with minimal cross-talk.
