Fig 1. Process for reconstructing brainstem nuclei and fiber tracts in 3D from 7T MRI.

Fig 1

The brainstem region outlined in blue (A) was cropped (B) from each coronal 7T SWI MR image. (C) An affine deformation algorithm based on user-defined seed points was used to warp contours from a rhesus macaque brain atlas to the MRI of each subject. The PPN is outlined in white. (D) Algorithm-defined contours from nuclei and fiber tracts within brainstem were outlined on each slice and then (E, F) lofted to create surface renderings.
