| Research Abstract |
For the purpose of the improvement of optical mapping technology which images brain functions noninvasively using near-infrared light, numerical simulations based on the analysis of light propagation in heads and phantom experiments were conducted. The effects of the non-scattering tissues such as the cerebrospinal fluid layer, eye ball and frontal sinus on the mapping images were investigated. Also the effects of the thick blood vessels lying at the brain surface were investigated. The results will contribute to better understanding of the mapping images and to improvement of the quality of the mapping images.
