Park HJ, Kubicki M, Westin CF, Talos IF, Brun A, Peiper S, Kikinis R, Jolesz FA, McCarley RW, Shenton ME AJNR Am J Neuroradiol 2004 Sep;25(8):1318-24 PMID: 15466325 Abstract We introduce a method for combining fiber tracking from diffusion-tensor (DT) imaging with cortical gray matter parcellation from structural high-spatial-resolution 3D… read more →
Brun A, Knutsson H, Park HJ, Shenton ME, Westin CF Med Image Comput Comput Assist Interv 2004 Sep;3216/2004(3216):368-375 PMID: 20209048 Abstract In this paper we present a framework for unsupervised segmentation of white matter fiber traces obtained from diffusion weighted MRI data. Fiber traces are compared pairwise to create a… read more →
Niethammer M, Bouix S, Westin CF, Shenton ME Med Image Comput Comput Assist Interv 2006;9(Pt 2):252-9 PMID: 17354779 Abstract Individual white matter fibers cannot be resolved by current magnetic resonance (MR) technology. Many fibers of a fiber bundle will pass through an individual volume element (voxel). Individual visualized fiber tracts… read more →
O’Donnell LJ, Kubicki M, Shenton ME, Dreusicke MH, Grimson WE, Westin CF AJNR Am J Neuroradiol 2006 May;27(5):1032-6 PMID: 16687538 Abstract BACKGROUND/PURPOSE: Despite its potential for visualizing white matter fiber tracts in vivo, diffusion tensor tractography has found only limited applications in clinical research in which specific anatomic connections between… read more →
Malcolm JG, Shenton ME, Rathi Y Med Image Comput Comput Assist Interv 2009;12(Pt 1):894-902 PMID: 20426073 Abstract We describe a technique to simultaneously estimate a weighted, positive-definite multi-tensor fiber model and perform tractography. Existing techniques estimate the local fiber orientation at each voxel independently so there is no running knowledge… read more →
Malcolm JG, Shenton ME, Rathi Y Inf Process Med Imaging 2009;21:126-38 PMID: 19694258 Abstract We describe a technique to simultaneously estimate a local neural fiber model and trace out its path. Existing techniques estimate the local fiber orientation at each voxel independently so there is no running knowledge of confidence… read more →
Rathi Y, Malcolm JG, Michailovich O, Westin CF, Shenton ME, Bouix S Magn Reson Med 2010 Jul;64(1):138-48 PMID: 20572129 Abstract This paper proposes a novel framework for joint orientation distribution function estimation and tractography based on a new class of tensor kernels. Existing techniques estimate the local fiber orientation at… read more →
Savadjiev P, Rathi Y, Malcolm JG, Shenton ME, Westin CF Med Image Comput Comput Assist Interv 2010;13(Pt 2):233-40 PMID: 20879320 Abstract We introduce a fibre tractography framework based on a particle filter which estimates a local geometrical model of the underlying white matter tract, formulated as a ‘streamline flow’ using… read more →
Malcolm JG, Shenton ME, Rathi Y IEEE Trans Med Imaging 2010 Sep;29(9):1664-75 PMID: 20805043 Abstract We describe a technique that uses tractography to drive the local fiber model estimation. Existing techniques use independent estimation at each voxel so there is no running knowledge of confidence in the estimated model fit.… read more →
