Paper Abstract

An non-invasive optical method for obtaining quantitative biochemical information is desirable. While quantitative methods for predicting fluorophore concentrations in dilute solutions are well known, human tissue is highly scattering and absorbing and cannot be accurately treated with these techniques. We have employed the method of partial least squares (PLS) to develop an empirical, linear model of sample fluorescence from a training set with optical properties and known concentrations representative of those to be predicted. This model can be applied to predict chromophore concentrations in the unknown samples.
