Paper Abstract

In this paper, we propose a partially reflecting boundary method for diffusive optical imaging of shallow targets in turbid media. An appropriate range of the effective reflection coefficient Reff has been suggested between 0.0 and 0.7, in which the extrapolated boundary condition can be used to simplify the forward model. For a shallow target of approximately 0.5 cm deep from the surface, experimental data acquired with a reflecting boundary of Reff ≈ 0.6 lead to significant improvement in the image quality compared with that from an absorbing boundary of Reff ≈ 0.
