Method and apparatus for estimating effective channel of functional near-infrared spectroscopy

摘要

Provide the effective localization method measured according to the brain activity of the near infrared ray spectroscopy of function. A kind of method, for determining that according to the effective position of the brain activity measurement of the near infrared ray spectroscopy of function include from near-infrared spectroscopy (fNIRS) the N Measurement channels acquisition cerebral blood flow (CBF) signal corresponding with multiple positions of scalp by function; Removal breathing, blood circulation, and the noise component(s) containing movement of the theme from the cerebral blood flow (CBF) signal obtained; Step before one processing divides sound cancelling signal and enters time series data for executing and stopping, and calculates hibernation classification body-building and allocation priority according to the classification body-building of calculating; If the association of the NM numbers of the poor channel of each M number relative to preferable channel is equal to or more than first reference value, the L numbers of poor channel are divided into ID=0. preferable channel RTI0M+L/RTIeffective channel.
