Diffusion Maps Clustering for Magnetic Resonance Q-Ball Imaging Segmentation
Figure 1
Funk-Radon transform illustrated for
the input diffusion attenuation signal ( s/mm2) with 1 fiber (left) and two
orthogonal fibers (right). The thin lines
are the true underlying fiber
directions and the thicker tubes are
the detected maxima. One must imagine
these functions as living on the surface
of the sphere. Here, for visualization
purposes, the radius of the respective
spheres are scaled by the corresponding
value on the surface. Blue-to-red colors
represent low-to-high spherical values.
