Venkataraman A, Kubicki M, Westin CF, Golland P Conf Comput Vis Pattern Recognit Workshops 2010;:63-70 PMID: 21660131 Abstract We propose an alternative to univariate statistics for identifying population differences in functional connectivity. Our feature selection method is based on a procedure that searches across subsets of the data to isolate… read more →
Venkataraman A, Kubicki M, Golland P Med Image Comput Comput Assist Interv 2012;15(Pt 1):715-22 PMID: 23285615 Abstract We propose a novel approach to identify the foci of a neurological disorder based on anatomical and functional connectivity information. Specifically, we formulate a generative model that characterizes the network of abnormal functional… read more →
Preti MG, Makris N, Laganà MM, Papadimitriou G, Baglio F, Griffanti L, Nemni R, Cecconi P, Westin CF, Baselli G Conf Proc IEEE Eng Med Biol Soc 2012;2012:2283-6 PMID: 23366379 Abstract Diffusion Tensor Imaging (DTI) tractography and functional Magnetic Resonance Imaging (fMRI) investigate two complementary aspects of brain networks: white… read more →
Savadjiev P, Campbell JS, Pike GB, Siddiqi K Med Image Comput Comput Assist Interv 2005;8(Pt 1):123-30 PMID: 16685837 Abstract We develop a differential geometric framework for regularizing diffusion MRI data. The key idea is to model white matter fibers as 3D space curves and to then extend Parent and Zucker’s… read more →
Savadjiev P, Campbell JS, Pike GB, Siddiqi K Med Image Comput Comput Assist Interv 2008;11(Pt 1):135-43 PMID: 18979741 Abstract We introduce a fibre tract segmentation algorithm based on the geometric coherence of fibre orientations as indicated by a streamline flow model. The inference of local flow approximations motivates a pairwise… read more →
Savadjiev P, Rathi Y, Bouix S, Verma R, Westin CF Med Image Comput Comput Assist Interv 2012;15(Pt 3):34-41 PMID: 23286111 Abstract The geometry of white matter tracts is of increased interest for a variety of neuroscientific investigations, as it is a feature reflective of normal neurodevelopment and disease factors that… read more →
Pasternak O, Sochen N, Gur Y, Intrator N, Assaf Y Magn Reson Med 2009 Sep;62(3):717-30 PMID: 19623619 Abstract Relating brain tissue properties to diffusion tensor imaging (DTI) is limited when an image voxel contains partial volume of brain tissue with free water, such as cerebrospinal fluid or edema, rendering the… read more →
Westin CF, Szczepankiewicz F, Pasternak O, Ozarslan E, Topgaard D, Knutsson H, Nilsson M Med Image Comput Comput Assist Interv 2014;17(Pt 3):209-16 PMID: 25320801 Abstract In traditional diffusion MRI, short pulsed field gradients (PFG) are used for the diffusion encoding. The standard Stejskal-Tanner sequence uses one single pair of such… read more →
Malcolm J, Rathi Y, Tannenbaum A Proc IEEE Comput Soc Conf Comput Vis Pattern Recognit 2008;:1-8 PMID: 23680693 Abstract This paper proposes a novel method to apply the standard graph cut technique to segmenting multimodal tensor valued images. The Riemannian nature of the tensor space is explicitly taken into account… read more →
