An in vivo method utilizing derivative near-infrared spectroscopy was developed to
noninvasively determine cerebral venous hemoglobin O2 saturation (SVO2). The method …

We present in vivo measurements of baseline physiology from five subjects with a four-
wavelength (690, 750, 800, and 850 nm) time-resolved optical system. The measurements …

Methods for measuring cerebral blood volume (CBV) have traditionally used radioisotopes.
More recently, near-infrared spectroscopy (NIRS) has been used to measure CBV by using …

A multispectral direct chromophore and scattering reconstruction technique has been
implemented for near-infrared frequency-domain tomography in recovering images of total …

A simple method to evaluate the hemoglobin oxygen saturation and relative hemoglobin
concentration in a tissue from diffuse reflectance spectra in the visible wavelength range is …

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) …

Near-infrared spectroscopy may allow continuous and noninvasive monitoring of regional
brain hemoglobin oxygen saturation by measuring the differential absorption of infrared light …

Although near-infrared spectroscopy (NIRS) was originally designed for clinical monitoring
of tissue oxygenation, it has also been developing into a useful tool for neuroimaging …

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

Since soft tissues, skin and bone are relatively translucent to near infrared (NIR) light and
since cytochrome c oxidase possesses a redox dependent absorption band in that region, it …
