Abstract

The partial optical path length and spatial sensitivity profile in the head model are predicted by a Monte Carlo simulation to analyze the influence of the hemodynamics in the scalp on the time-gated NIRS imaging using null source-detector separation. The simple subtraction of the NIRS signal detected within the early gate time from that within the late gate time is effective to remove the influence of the hemodynamic signal from the scalp in the brain function image.
