Optical brain functional imaging system

摘要

PPROBLEM TO BE SOLVED: To provide an optical cerebral function imaging apparatus capable of preventing a device structure from becoming complicated and a cost from increasing, solving the problem caused by wavelength dependency with light to be irradiated in an optical measurement method, and correctly performing a statistic test. PSOLUTION: The optical cerebral function imaging apparatus 1 includes: a light emission/reception part control part 4 for obtaining the respective temporal changes XSBn/SB(t) of signal values ASBn/SBconcerning cerebral activities in N measurement parts on the cerebral surface of a subject; a general linear model generating part 31 for expressing the temporal changes XSBn/SB(t) of the signal values ASBn/SBwith the use of general linear models YSBn/SB(t); a t-value calculating part 32 for calculating t-vales for performing the test concerning a plurality of partial regression coefficients SBp/SB; and a t-testing part 33 for testing significance of the general linear models YSBn/SB(t). The signal value ASBn/SBis a voltage value ratio or absorbance. PCOPYRIGHT: (C)2009,JPO&INPIT
