Abstract
A laser transillumination tomographic system, using red and near infrared l asers, to obtain cross-sectional images of human breast phantoms and human hand is proposed. The scanning assembly is consisting of upward, downward, rotational and pitch movements. The phantoms, made of paraffin wax, agar ge l, and milk placed in a glass model, are embedded with abnormalities like b lood, water, solid objects, and tissues. By illuminating the phantoms at va rious heights by either red or infrared laser the projection data are colle cted. Based on 64 projections the tomogram of each section is constructed. By volume visualization procedure applied to the tomograms the objects of v arying composition embedded within the phantoms are detected and their size , shape, and location depth are determined. The cross-sectional image of a human hand obtained by this procedure further shows the possibility of appl ication of this technique for imaging of organs.
