Method and Device for removing noise from Functional near-infrared spectroscopy signal

摘要

As a preferred embodiment of the present invention, an apparatus for removing noise from a near-infrared spectral signal is fNIRS that acquires a hemodynamic response signal from a plurality of measurement channels output when irradiating a near-infrared signal at a plurality of locations on the scalp by functional near-infrared spectroscopy. A signal acquisition unit; a multi-threshold value calculation unit that calculates a threshold value Γ
