Abstract
An imaging method ( ) for imaging a subject ( ) including fibrous or anisotropic structures ( ) includes acquiring a three-dimensional apparent diffusion tensor map ( ) of a region with some anisotropic structures ( ). The apparent diffusion tensor at a voxel is processed ( ) to obtain eigenvectors (e , e , e ) and eigenvalues (&lgr; , &lgr; , &lgr; ). A three-dimensional fiber representation ( ) is extracted ( ) using the eigenvectors and eigenvalues. During the extracting ( ), voxels are locally interpolated ( ) in at least a selected dimension in a vicinity of the fiber representation ( ). The interpolating includes weighting the voxels by a parameter indicative of a local anisotropy. The interpolating results in a three-dimensional fiber representation ( ) having a higher tracking accuracy and representation resolution than the acquired tensor map ( ).
