ØSimilarly, can cutout
everything Anterior to, Posterior to, or Superior to, Inferior to,

å BehindÉ, BelowÉ, FrontÉ, AboveÉ

For
example, Above
AS-PI is above a plane that
slants from the Anterior-Superior frontof
the brain downwards to the Posterior-Inferior
back of the brain -- that is, halfwaybetween
a coronal and axial sliceå TT Ellipsoid cuts out the region outside an ellipsoid
with the same proportions
as the Talairach-Tournoux
Atlas brain
