Abstract

Diffuse Photon Density Waves (DPDW) is new concept and principle, which takes advantage of the difference of absorption and scattering coefficients of different tissues to study the law of photon density fluctuation during a modulated light traveling through the tissues, thus to explore the structure and function of tissues. With the combination of image reconstruction technology, we can directly `visualize' the tissues. As a non- invasive exam, it has highly extensive applied prospect in medical field and brain cognition study. In this paper, the behavior of DPDW traveling through simulated breast tissue is tentatively examined. Under various conditions, we observed the characteristics of DPDW. We observed the reasonability of the distribution of sources and detectors, the factors that influence the distortion of DPDW. Simulation results could be used as a good theoretical guideline for experiments.
