Regularized positive-definite fourth order tensor field estimation from DW-MRI
In Diffusion Weighted Magnetic Resonance Image (DW-MRI) processing, a 2nd order tensor has been commonly used to approximate the diffusivity function at each lattice point of the DW-MRI data. From this tensor approximation, one can compute useful scalar quantities (e.g. anisotropy, mean diffusivity) which have been clinically used for monitoring encephalopathy, sclerosis, ischemia and other bra...
متن کاملEstimation of symmetric positive-definite matrices from imperfect measurements
In a number of contexts relevant to control problems, including estimation of robot dynamics, covariance, and smart structure mass and stiffness matrices, we need to solve an over-determined set of linear equations AX ≈ B with the constraint that the matrix X be symmetric and positive definite. In the classical least squares method the measurements of A are assumed to be free of error, hence, a...
متن کاملEstimation of Extracellular Volume from Regularized Multi-shell Diffusion MRI
Diffusion MRI measures micron scale displacement of water molecules, providing unique insight into microstructural tissue architecture. However, current practical image resolution is in the millimeter scale, and thus diffusivities from many tissue compartments are averaged in each voxel, reducing the sensitivity and specificity of the measurement to subtle pathologies. Recent studies have point...
متن کاملRegularized diffusion tensor MRI for high angular resolution ODF estimation and fibre tractography
J. S. Campbell, P. Savadjiev, G. B. Pike, K. Siddiqi Montreal Neurological Institute, Montreal, Quebec, Canada, McGill Centre for Intelligent Machines, Montreal, Quebec, Canada Introduction High angular resolution diffusion (HARD) MRI can be used to infer multiple subvoxel fibre directions [1-2], and this information can be used to improve the precision of fibre tractography over that achieved ...
متن کاملSimultaneous Smoothing and Estimation of the Tensor Field from Diffusion Tens or MRI
Diffusion tensor magnetic resonance imaging (DT-MRI) is a relatively new imaging modality in the field of medical imaging. This modality of imaging allows one to capture the structural connectivity if any between functionally meaningful regions for example, in the brain. The data however can be noisy and requires restoration. In this paper, we present a novel unified model for simultaneous smoo...
