Abstract
In this study, the light propagation in a three-dimensional realistic head model is calculated by the finite difference method to obtain topographic images of brain activity. The topographic images obtained by two types of source-detector arrangement are compared to evaluate the efficiency of source-detector arrangement. The results show that the double density arrangement improves the quality of the topographic image of the brain activity.
