ABSTRACT


Description. This unique, animated fly-through navigates a complex brain dataset that is difficult to appreciate using static visualization. Novel C++ 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.
