Near Infrared Absorption Imaging of Dense Scattering Media by Steady-State Diffusion Tomography

H.L. Graber et al. (1993)


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 (<1 mm edge detection) images are recoverable of small-diameter objects buried at depths not visible from the surface.
