Paper Abstract

Numerical solutions to the diffusion equation describing light propagation in tissues are presented. The results show that time- dependent measurements of light propagation can be used to monitor the fluorescent lifetimes of a fluorophore uniformly distrusted in tissues. With proper referencing, frequency-domain measurements of phase-shift, (Theta) , may allow quantitation of fluorescent lifetimes, (tau) , independent of changes in the local absorption and scattering properties. These results point to a new approach for noninvasive diagnostic monitoring through quantitation of fluorescent lifetimes, (tau) .
