3D glyphs visualizing diffusion tensors. The orientation and sharpness of the glyphs depend on the eigenvectors and eigenvalues of the diffusion tensor, respectively. In this image, the glyphs have been colored according to the orientation of the main eigenvector (e.g., a main eigenvector of (1,0, 0) corresponds to a red glyph, while a main eigenvector of (0,0, 1) corresponds to a blue glyph). This image was generated in the DTITool [11].
