Pohl KM, Fisher J, Levitt JJ, Shenton ME, Kikinis R, Grimson WE, Wells WM Med Image Comput Comput Assist Interv 2005;8(Pt 1):310-8 PMID: 16685860 Abstract We present a statistical framework that combines the registration of an atlas with the segmentation of magnetic resonance images. We use an Expectation Maximization-based algorithm… 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 →
