The paper is devoted to the problems of design of reconstruction algorithms for optical diffuse tomography (ODT). To reconstruct tissue optical inhomogeneities, a new method based on a concept of an average statistical trajectory for transfer of light energy (photon average trajectory, PAT) is proposed. Several analogies of curvilinear PAT in strongly scattering media with the usual optics rays are presented. It is shown that the PAT method is convenient for the time-domain optical diffuse tomography as well as for the frequency-domain one. The use of the trajectory approach opens promising opportunities for the increasing of the spatial resolution using methods designed in the convenient optics.© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering.
