Geometries and data considered in this work. (a) Axial and coronal slices through the subregion \( \Omega \) of the white matter we consider in this work. The green region depicts the gray matter and is drawn to illustrate the geometrical complexity of the grey matter. (b) Axial view of the tracer concentration after 24Â h in the right hemisphere for the three data sets under consideration. Note how the tracer enters the brain from CSF spaces (black).
