Near-infrared absorption imaging of dense scattering media by steady-state diffusion tomography

摘要

Abstract: Results of experimental studies are presented based on steady- state optical tomographic measurements performed at 720 nm on tissue-like media having cylindrical geometry and a thickness equivalent to an uncompressed female breast. Experimental data were evaluated using a linear perturbation equation, previously described, derived from the transport equation. Results obtained demonstrate that high-resolution ($LS 1 mm edge detection) images are recoverable of small-diameter objects buried at depths not visible from the surface. !17
