Paper Abstract

We demonstrate successful image reconstruction based on experimental data obtained with a cw HeNe laser system in a laboratory phantom having two optically distinct regions. The experimental system which presently supplies intensity only measurements exploits a tomographic type of data collection scheme that provides information from which a spatially variable optical diffusion coefficient map is deduced. Different types of boundary constraints have been considered and the images produced indicate that the zero average intensity boundary constraint results in better imaging quality. While the cw optical system used in these experiments is crude, and the physical phantom imaged is highly idealized, the results suggest that tomographic data collection coupled to a finite element image formation algorithm offers a potentially powerful approach for biologically based optical imaging.
