SYSTEMS AND METHODS FOR DETERMINING HEMOGLOBIN CONCENTRATION UTILIZING DIFFUSE REFLECTANCE AT ISOSBESTIC WAVELENGTHS

摘要

Systems and methods for determining hemoglobin concentration utilizing diffuse reflectance at isosbestic wavelengths are provided. In one embodiment, the method includes emitting light onto a tissue mass, measuring diffuse reflectance from the tissue mass, and calculating a ratio of diffuse reflectance intensities at two isosbestic wavelengths using the measured diffuse reflectance. The method also includes determining a hemoglobin concentration associated with the tissue mass by applying the calculated ratio to a predefined analytical expression associated with the two isosbestic wavelengths.
