¥Surface Geometry:
Hrefers to the
spatial coordinates of the nodes forming the surface model
¥Surface Topology:
Hrefers to the
connectivity between nodes forming the surface model
¥Models with different
geometry but similar topology are created for each surface
model.
Hwhite/grey, pial,
inflated, spherical, flattened, etc.
¥Some modelsÕ geometries are
anatomically correct
HPial and/or white
matter surfaces can be used for relating to volume
data.
HInflated, flattened
and spherical cannot be directly linked to volume data. The link
is done via their corresponding anatomically-correct
surfaces.
