Fully 3D reconstruction of attenuation for diffuse optical tomography using a finite element model

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...

Description
Summary: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.
