Abstract:
An imaging method for imaging a subject including anisotropic structures, the method comprising:acquiring a three-dimensional apparent diffusion tensor map of at least a portion of the subject including at least some anisotropic structures; processing the apparent diffusion tensor map at a voxel to obtain eigenvectors and eigenvalues; tracking a three-dimensional fiber representation using the eigenvectors and eigenvalues; rendering the three-dimensional fiber representation as a hyperstreamline representation having a direction corresponding to a direction of the three-dimensional fiber representation and a cross-section indicative of diffusion anisotropy; generating a background image representation of the portion of the subject corresponding to the three-dimensional apparent diffusion tensor map; and producing a human-viewable display including the hyperstreamline representation superimposed on the background image representation.
