This unique, animated fly-through navigates a complex brain dataset that
is difficult to appreciate using static visualization.
supercomputing algorithms, running on a 32-processor SGI RealityMonster,
determined how brain structure varies across normal individuals, based
on 20 subjects' MRI scans.
The camera trajectory navigates through
cortical, sulcal and ventricular brain regions containing transparent
ellipsoidal glyphs (tensors), showing the directions and magnitude of
anatomic variability (pink colors: greatest, blue: least). Rendering the
animated path requires up to 10 CPU hours per frame, in dense regions
with thousands of transparent surfaces overlaid. Such data assists in
the detection of Alzheimer's disease.
