The basic parameters for physiological measurements provided by near-infrared
spectroscopy are the local absorption and scattering coefficients. For the adult human head …

We present near-infrared spectroscopy measurement of absolute cerebral hemoglobin
concentration and saturation in a large sample of 36 healthy elderly (mean age, 85±6 years) …

Combining spatially-and time-resolved spectroscopies, we attempted to quantitatively
evaluate the contribution ratio of the partial mean pathlength of cerebral tissue to the …

In near-infrared spectroscopy and imaging, the sensitivity of the detected signal to brain
activation and the volume of interrogated tissue are clinically important. Light propagation in …

Near-infrared spectroscopy (NIRS) is a noninvasive method of quantifying changes in
cerebral haemodynamics from changes in the absorption of near-infrared light by …

We investigate the optical properties of the brain in 23 neonates in vivo using a frequency
domain near-infrared spectroscopy (NIRS). In this study, a calibration procedure is …

Theoretical analysis of spatial distribution of near-infrared light propagation in head tissues
is very important in brain function measurement, since it is impossible to measure the …

This project had two main objectives. The first of these was to design and construct a
spectroscopic instrument to monitor small changes in optical transmission across an infant's …

Near-infrared spectroscopy (NIRS) is a noninvasive technique for continuous monitoring of
the amounts of total hemoglobin (total-Hb), oxygenated hemoglobin,(oxy-Hb) and …

Objective. To examine the effect of two emitter-detector separations (2.7 and 5.5 cm) on the
detection of changes in cerebral and extra-cerebral tissue oxygenation using near infrared …
