摘要：A concentration measurement apparatus includes a probe 20, having a lightincidence section making measurement light incident on the head and a light detection

section detecting the measurement light that has propagated through the interior of thehead, and a CPU 14 determining temporal relative change amounts of oxygenatedhemoglobin concentration and deoxygenated hemoglobin concentration and

determining a correlation coefficient of the relative change amounts and a polarity of aslope of a regression line. A concentration measurement apparatus and a concentrationmeasurement method that enable evaluation of the accuracy of calculation and thepossibility of reverse direction blood transmission from the vena cava to the head basedon the phase shift between the oxygenated hemoglobin concentration and thedeoxygenated hemoglobin concentration are thereby realized.
