Abstract

The scalp-cortex correlation (SCC) is important for the brain activity measurements by functional near-infrared spectroscopy. A physical head surface model was manufactured to accurately determine the probe positions mounted on the probe holder attached to the head. The coordinates of the probe positions measured in the physical space were mapped to the surface of the virtual head model. The light propagation in the virtual head model was calculated to obtain the spatial sensitivity profile and normalized partial optical path length for the evaluation of the SCC.
