abstract = {3D-Polarized Light Imaging has become a unique technique to
study the fiber architecture of unstained brain sections at
the meso- and microscale. It exploits the intrinsic
birefringence of nerve fibers which is measured with a
customized Polarimeter in which the brain section is placed
on a tiltable specimen stage. So far, a computationally fast
analytical method based on the discrete Fourier
transformation to analyze the data acquired with the
tiltable specimen stage has been used. In this study, we
propose a new algorithm based on a fitting approach which
provides an improved stability against measurement noise
resulting in a more realistic orientation interpretation, in
particular for low signals. For the first time, it is
demonstrated how fiber courses at the boundary of white and
grey matter can robustly be reconstructed with 3D-PLI. This
significantly improves the reliability of mapping the cortex
based on 3D-PLI data.},
