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.
