Abstract
The random walk theory was used to addressed the interrelated elements required for clinically useful imaging, by calculating a time-dependent contrast function to describe photon paths in time-resolved transillumination detection of abnormally absorbing and scattering regions in tissue. Results of the theory were applied to estimate the absorption and the scattering coefficients of a cylinder embedded in a tissue-like phantom. A random walk model was applied for the characterization of photon paths within the tissue as a basis for inverse imaging algorithms. The model for photon migration used found exact expression for the frequency-dependent fluorescent signal emitted from a single fluorescent site embedded in tissue.
