The laser backscattering from biological tissues depends on their composition and blood flow. The onset of abnormalities in tissues is associated with the change in composition at a specific location which may affect laser backscattering. The objective of this work is to study the point-to-point compositional variation of male breast tissues as this site(More)
Tissue equivalent phantoms were made by mixing various combinations of wax colors with paraffin wax. Abnormalities of various size and shape were embedded into the tissue equivalent phantoms at different locations and depths to simulate real life abnormalities of tissues. The normalized back-scattered intensity (NBI) profiles at various locations on the(More)
The normalized back-scattered intensity (NBI) profiles at various locations on the human thorax of a subject were obtained by multi-probe laser reflectometer. The laser radiations are guided by an optical fiber onto the human thorax tissues and the backscattered radiations are collected by three optical fibers placed at distance of 2 mm, 4 mm and 6 mm from(More)
The normalized backscattered intensity (NBI) profiles at various locations of human thorax by multiprobe laser reflectometer are obtained. These data after digitization, interpolation, and filtering are color-coded and displayed as images on the outline of the human thorax. For optical characterization of tissues in terms of their parameters, scattering and(More)
