Voineskos AN, Lobaugh NJ, Bouix S, Rajji TK, Miranda D, Kennedy JL, Mulsant BH, Pollock BG, Shenton ME Brain 2010 May;133(Pt 5):1494-504 PMID: 20237131 Abstract In healthy adult individuals, late life is a dynamic time of change with respect to the microstructural integrity of white matter tracts. Yet, elderly individuals… read more →
Sasson E, Doniger GM, Pasternak O, Assaf Y Neuroimage 2010 Apr;50(3):1231-42 PMID: 20045476 Abstract Aging is associated with a variety of structural and pathological brain changes. Memory, or the ability to store and retrieve information, declines significantly during aging. In order to characterize the brain micro-structural correlates of memory performance,… read more →
Vaswani N, Rathi Y, Yezzi A, Tannenbaum A IEEE Trans Image Process 2010 Apr;19(4):841-57 PMID: 19933014 Abstract We propose algorithms for tracking the boundary contour of a deforming object from an image sequence, when the nonaffine (local) deformation over consecutive frames is large and there is overlapping clutter, occlusions, low… read more →
Savadjiev P, Kindlmann GL, Bouix S, Shenton ME, Westin CF Neuroimage 2010 Feb;49(4):3175-86 PMID: 19896542 Abstract We introduce a mathematical framework for computing geometrical properties of white matter fibers directly from diffusion tensor fields. The key idea is to isolate the portion of the gradient of the tensor field corresponding… read more →
Michailovich O, Rathi Y IEEE Trans Image Process 2010 Feb;19(2):461-77 PMID: 19887312 Abstract Visualization and analysis of the micro-architecture of brain parenchyma by means of magnetic resonance imaging is nowadays believed to be one of the most powerful tools used for the assessment of various cerebral conditions as well as… read more →
Pasternak O, Sochen N, Basser PJ Neuroimage 2010 Feb;49(3):2190-204 PMID: 19879947 Abstract The measurement of the distance between diffusion tensors is the foundation on which any subsequent analysis or processing of these quantities, such as registration, regularization, interpolation, or statistical inference is based. In recent years a family of Riemannian… read more →
Malcolm JG, Michailovich O, Bouix S, Westin CF, Shenton ME, Rathi Y Med Image Anal 2010 Feb;14(1):58-69 PMID: 19914856 Abstract We propose a technique to simultaneously estimate the local fiber orientations and perform multi-fiber tractography. Existing techniques estimate the local fiber orientation at each voxel independently so there is no… read more →
Napadow V, Dhond R, Park K, Kim J, Makris N, Kwong KK, Harris RE, Purdon PL, Kettner N, Hui KK Neuroimage 2009 Aug;47(1):289-301 PMID: 19345268 Abstract Acupuncture modulation of activity in the human brainstem is not well known. This structure is plagued by physiological artifact in neuroimaging experiments. In addition,… read more →
Kawashima T, Nakamura M, Bouix S, Kubicki M, Salisbury DF, Westin CF, McCarley RW, Shenton ME Schizophr. Res. 2009 May;110(1-3):119-26 PMID: 19328656 Abstract Two of the most frequently investigated regions in diffusion tensor imaging studies in chronic schizophrenia are the uncinate fasciculus (UF) and cingulum bundle (CB). The purpose of… read more →
Levitt JJ, Styner M, Niethammer M, Bouix S, Koo MS, Voglmaier MM, Dickey CC, Niznikiewicz MA, Kikinis R, McCarley RW, Shenton ME Schizophr. Res. 2009 May;110(1-3):127-39 PMID: 19328654 Abstract BACKGROUND: Previously, we reported abnormal volume and global shape in the caudate nucleus in schizotypal personality disorder (SPD). Here, we use… read more →
