2-D Structure Reconstruction for a DOT Method based on Linear Perturbation Approach

Abstract

Biological imaging with a method for diffusion optical tomography is demonstrated. The present method is based on weight function of discrete model for scattering tissues. The weight function is given as a product form between sensitivity function and optical mean path length. The method is applied to two-dimensional imaging for inhomogeneous media by simulation. As results of the simulation, it is verified that the present method can extract parts with stronger absorption coefficient from backgrounds.
