Current denoising methods for diffusion weighted images can obtain high quality estimates of local fiber orientation in static structures. However, recovering reliable fiber orientation from in vivo data is considerably more difficult. To address this problem we use a geometric approach, with a spatio-temporal Cartan frame field to model spatial (within time-frame) and temporal (between time-frame) rotations within a single consistent mathematical framework. The key idea is to calculate the… Expand

Cartan Frames for Heart Wall Fiber Motion
TLDR
A moving frame method is developed that shows promise in providing Cartan connection parameters to describe spatio-temporal rotations of fibers, which in turn could benefit subsequent analyses or be used for diagnostic purposes. Expand
In vivo human cardiac fibre architecture estimation using shape-based diffusion tensor processing
TLDR
This article presents a method to analyse the fibre architecture of the left ventricle (LV) using shape-based transformation into a normalised Prolate Spheroidal coordinate frame and shows the advantages of using curvilinear coordinates both for the anaylsis and the interpolation of cardiac DTI information.

Maurer-Cartan Forms for Fields on Surfaces: Application to Heart Fiber Geometry
TLDR
Direct local measurements of the variation of the helix and transverse angles, of fiber fanning and twisting, and of the curvatures of the heart wall in which these fibers lie are obtained. Expand
Diffusion Weighted Image Denoising Using Overcomplete Local PCA
TLDR
This new filter reduces random noise in multicomponent DWI by locally shrinking less significant Principal Components using an overcomplete approach and is compared with state-of-the-art methods using synthetic and real clinical MR images, showing improved performance in terms of denoising quality and estimation of diffusion parameters.

A Novel Rule-Based Algorithm for Assigning Myocardial Fiber Orientation to Computational Heart Models
TLDR
A novel Laplace–Dirichlet Rule-Based (LDRB) algorithm is presented to perform this task with speed, precision, and high usability and convincingly show that the LDRB algorithm is a robust alternative to DTI for assigning fiber orientation to computational heart models. Expand
Impact of Rician Adapted Non-Local Means Filtering on HARDI
TLDR
The results suggest that the NLMr filtering improve the quality of anisotropy maps computed from ADC and ODF and improve the coherence of q-ball ODFs with the underlying anatomy while not degrading angular resolution. Expand
Whole heart DTI using asymmetric bipolar diffusion gradients
TLDR
The aim of this study was to develop SE-based cardiac diffusion MRI protocol with second order moment nulling, thus also compensating for acceleration, and to compare its performance to that of Stejskal-Tanner and bipolar gradients waveforms. Expand
An Optimized Blockwise Nonlocal Means Denoising Filter for 3-D Magnetic Resonance Images
TLDR
The results show that the optimized NL-means filter outperforms the classical implementation of the NL- means filter, as well as two other classical denoising methods and total variation minimization process in terms of accuracy with low computation time. Expand

TLDR
This paper treats the left ventricular myocardium as a non-homogeneous, thick-walled, nonlinearly elastic and incompressible material and develops a general theoretical framework based on invariants associated with the three directions, then develops a structurally based model that accounts for the muscle fibre direction and the myocyte sheet structure.
