  • Abstract
    In this study, we present reconstruction results for optical tomography based on measurements with a 3D scanner using a finite element forward model. We show the importance of taking the correct Green´s function everywhere, which is possible using the FEM approach. Further, it is shown that for the simple case of a few spheres in a homogeneous liquid, the Rytov approximation suffices.
