Snake-based brain white matter fiber reconstruction.
Diffusion tensor imaging (DTI) is a tractography algorithm that provides the only means of mapping white matter fibers. Furthermore, because of its wealth of applications, diffusion MRI tractography is gaining importance in clinical and neuroscience research. This paper presents a novel brain white matter fiber reconstruction method based on the snake model by minimizing the energy function, wh...

متن کاملIllustrative White Matter Fiber Bundles
Diffusion Tensor Imaging (DTI) has made feasible the visualization of the fibrous structure of the brain white matter. In the last decades, several fiber-tracking methods have been developed to reconstruct the fiber tracts from DTI data. Usually these fiber tracts are shown individually based on some selection criteria like region of interest. However, if the white matter as a whole is being vi...
متن کاملFiber tract-based atlas of human white matter anatomy.
Two- and three-dimensional (3D) white matter atlases were created on the basis of high-spatial-resolution diffusion tensor magnetic resonance (MR) imaging and 3D tract reconstruction. The 3D trajectories of 17 prominent white matter tracts could be reconstructed and depicted. Tracts were superimposed on coregistered anatomic MR images to parcel the white matter. These parcellation maps were the...
متن کاملWhite matter fiber orientation mapping based on T2* anisotropy
Introduction Recent studies have shown that T2 relaxation may be anisotropic [1-4]. This anisotropy has been attributed to the microscopic (sub-voxel level) anisotropic distribution of susceptibility perturbers. In white matter fiber bundles, these anisotropic pertubations could originate from compounds such as lipid and ferritin that may align with axons, and could generate magnetic field vari...
