Abstract
The present disclosure relates to a method and a system for quantifying a biomarker of a biological tissue. Two spectral sub-intervals are determined from a plurality of images of the tissue acquired at discrete wavelengths within a main wavelength interval using an imaging sensor in a manner such that the combination of the image data in the at least two spectral sub-intervals are correlated with a clinical variable of interest. The tissue is illuminated using one or more light sources with wavelengths within the at least two spectral sub-intervals. A measurement is of the light reflected by the tissue is acquired using an imaging sensor; and a measure of the biomarker of the tissue is calculated using the acquired measurement. The main wavelength interval is broader than each of the at least two spectral sub-intervals and at least one spectral confounder causing a spectral variability of the acquired image is present in the tissue.
