¥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.
