Local white matter geometry from diffusion tensor gradients
(Elsevier BV, 2010)
We introduce a mathematical framework for computing geometrical properties of white matter fibres directly from diffusion tensor fields. The key idea is to isolate the portion of the gradient of the tensor field corresponding ...
A filtered approach to neural tractography using the Watson directional function
(Elsevier BV, 2010)
We propose a technique to simultaneously estimate the local fiber orientations and perform multifiber tractography. Existing techniques estimate the local fiber orientation at each voxel independently so there is no running ...
Electrophysiological and diffusion tensor imaging evidence of delayed corollary discharges in patients with schizophrenia
(Cambridge University Press (CUP), 2010)
Patients with schizophrenia (SZ) characteristically exhibit supranormal levels of cortical activity to self-induced sensory stimuli, ostensibly because of abnormalities in the neural signals (corollary discharges, CDs) ...
Tensor kernels for simultaneous fiber model estimation and tractography
(Wiley-Blackwell, 2010)
This paper proposes a novel framework for joint orientation distribution function (ODF) estimation and tractography based on a new class of tensor-kernels. Existing techniques estimate the local fiber orientation at each ...
