Abstract
A devise NIRS (Near Infrared Spectroscopy) can measure brain activation with infrared light. That’s because NIRS is expected to various applied studies about brain measurement. However spatial resolution of NIRS is poor, which is disadvantage of NIRS. In order to overcome this disadvantage, we study for better analysis method of NIRS data. We define inverse problem about NIRS measurement and estimate brain activation position from observational result of NIRS measurement. As a result of considering the structure of the brain and performed numerical experiments by our method, it was found that estimation of the depth direction and local position is difficult but there is improvement potential about NIRS disadvantage.
