Using both experimental and theoretical methods, we examine the contribution of different
parts of the head to near-IR (NIR) signal. Time-resolved spectroscopy is employed to …

Near‐infrared spectroscopy (NIRS), a noninvasive optical technique, can measure changes
in hemoglobin (Hb) concentrations in brain tissue. Jöbsis first described the in vivo …

Measurement of multichannel continuous-wave near-infrared spectroscopy (CW-NIRS) is
dependent on the modified Beer-Lambert law, which includes optical pathlength (PL) as an …

It is important for near-infrared spectroscopy (NIRS) and imaging to estimate the sensitivity of
the detected signal to the change in hemoglobin that results from brain activation and the …

Previous modeling of near-infrared (NIR) light distribution in models of the adult head
incorporating a clear nonscattering cerebrospinal fluid (CSF) layer have shown the latter to …

Using the visible Chinese human data set, which faithfully represents human anatomy, we
visualize the light propagation in the head in detail based on Monte Carlo simulation. 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 …

Although near‐infrared spectroscopy (NIRS) was developed as a tool for clinical monitoring
of tissue oxygenation, it also has potential for neuroimaging. A wide range of different NIRS …

Adequate modeling of light propagation in a human head is important for quantitative near-
infrared spectroscopy and optical imaging. The presence of a nonscattering cerebrospinal …

Brain activity is associated with changes in optical properties of brain tissue. Optical
measurements during brain activation can assess haemoglobin oxygenation, cytochrome-c …
