Diffusion Tensor Imaging (DTI) is a non-invasive imaging technique thatallows estimation of the location of white matter tracts in-vivo, based on themeasurement of water diffusion properties. For each voxel, a second-ordertensor can be calculated by using diffusion-weighted sequences (DWI) that aresensitive to the random motion of water molecules. Given at least 6diffusion-weighted images with different gradients and one unweighted image,the coefficients of the symmetric diffusion tensor matrix can be calculated.Deriving the eigensystem of the tensor, the eigenvectors and eigenvalues can becalculated to describe the three main directions of diffusion and itsmagnitude. Using DTI data, fiber bundles can be determined, to gain informationabout eloquent brain structures. Especially in neurosurgery, information aboutlocation and dimension of eloquent structures like the corticospinal tract orthe visual pathways is of major interest. Therefore, the fiber bundle boundaryhas to be determined. In this paper, a novel ray-based approach for boundaryestimation of tubular structures is presented.
