| Zusammenfassung | The photon Transport in highly scattering media is described by the diffusion equation, known to be the P1 - approximation of the Boltzmann Transport equation considering the absorption and scattering as parameter functions. The resulting parabolic differential equation for the photon density has been integrated by a Finite Element Method (FEM). Input data for the optical tomography correspond to the time-resolved transmittance, that means to the output photon flux on the boundary, at some detector positions for a number of photon sources working in succession. Strategies for an iterative reconstruction method are introduced and demonstrated by examples. |
