²Most cutout types are controlled by a single numerical
parameter determining the position of the
cutout
å Right of ÕxÕ means to cut out all voxels to the right of the
given x-coordinates (-x is Right, +x is Left)
ØSimilarly, can cutout everything Anterior to, Posterior
to, or Superior to, Inferior to, or Left of
a given coordinate position
å BehindÉ, BelowÉ, FrontÉ, AboveÉ
cut out 45o diagonally slanted half-spaces, with respect to the listed planes:
å
Ø For
example, Above
AS-PI is above a plane
Ø that
slants from the Anterior-Superior front
Ø of the
brain downwards to the Posterior-
Ø Inferior
back of the brain -- that is, halfway
Ø between
a coronal and axial slice
å
å TT Ellipsoid cuts out the region outside an ellipsoid
with the same proportions as the
Talairach-Tournoux
Atlas brain

but not much use
