DIFFUSION TENSOR MAGNETIC RESONANCE IMAGING INCLUDING FIBER RENDERING USING HYPERSTREAMLINES

摘要

An imaging method for imaging a subject (16) including anisotropic or fibrous structures (102) includes acquiring a three-dimensional apparent diffusion tensor map (44, 162) of a region with some anisotropic structures (102). The apparent diffusion tensor map (44, 162) is processed to obtain ordered eigenvectors and eigenvalues (48, 166) of diffusion tensor map voxels. A three-dimensional fiber representation (54, 208) is tracked using the eigenvectors and eigenvalues (48, 166). The three-dimensional fiber representation (54, 208) is rendered as a hyperstreamline representation (238). An background image representation (328) is generated. A human-viewable display (344) is produced including the rendered hyperstreamline representation (238) superimposed on the generated image background representation (328).
