The authors introduce a simple method to characterize optical properties and blood
oxygenation in tissue using spatially resolved, steady-state reflectance. The method …

Describes a simple technique for noninvasively determining the absolute concentration of
deoxyhaemoglobin (Hb) in living tissue using near infrared spectroscopy (NIRS). The …

A simple continuous wave near-infrared algorithm for estimating local hemoglobin oxygen
saturation in tissue (% StO 2) is described using single depth attenuation measurements at …

Near-infrared spectroscopy (NIRS) can be used to noninvasively measure changes in the
concentrations of oxy-and deoxyhemoglobin in tissue. We have previously shown that while …

A noninvasive method of measuring hemoglobin flow through an organ by near-infrared
spectroscopy (NIRS) is described that allows blood flow to be calculated. The method is …

The relative transparency of tissues to near infrared light means that it is possible to
transilluminate intact organs. In the infrared region, oxygen dependent absorptions due to …

Non–invasive techniques for the study of human brain function based on changes of the
haemoglobin content or on changes of haemoglobin saturation have recently been …

The principle of near infrared spectroscopy (NIRS) was first clearly defined by Jobsis in
1977, and recent technical and methodological advances have made it possible to use …

Extinction coefficients of hemoglobin have been studied for five decades by clinical chemists
and biochemists, particularly for laboratory spectrophotometric measurements. In the last ten …

Non invasive infrared spectroscopy is a well established technique for monitoring changes
in the oxygenation status of tissues (1). The technique has in particular been successfully …
