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 …

Wavelength selection and prediction algorithm for determining total hemoglobin
concentration are investigated. A model based on the difference in optical density induced …

A portable tissue oximeter that uses light-emitting diodes and two-wavelength near infrared
