Motion Detection in Diffusion MRI via Online ODF Estimation
The acquisition of high angular resolution diffusion MRI is particularly long and subject motion can become an issue. The orientation distribution function (ODF) can be reconstructed online incrementally from diffusion-weighted MRI with a Kalman filtering framework. This online reconstruction provides real-time feedback throughout the acquisition process. In this article, the Kalman filter is f...
متن کاملImage Analysis for Heart Motion in Tagged MRI
Tagged Magnetic Resonance Imaging is a very important method for the precise, non-invasive estimation of heart motion. In tagged MRI, regions of the tissue under study are magnetized in such a way to make them easily distinguishable in the resulting image. The magnetic pattern is embedded in the tissue so that the magnetized regions, usually in the form of concentric or parallel lines, will fol...
متن کاملImage decomposition with anisotropic diffusion applied to leaf-texture analysis
Texture analysis is an important field of investigation that has received a great deal of interest from computer vision community. In this paper, we propose a novel approach for texture modeling based on partial differential equation (PDE). Each image f is decomposed into a family of derived sub-images. f is split into the u component, obtained with anisotropic diffusion, and the v component wh...
متن کاملTagged cardiac MRI: detection of myocardial boundaries by texture analysis
The noninvasive evaluation of the cardiac function presents a great interest for the diagnosis of cardiovascular diseases. Cardiac tagged MRI allows the measurement of anatomical and functional myocardial parameters. This protocol generates a dark grid which is deformed with the myocardium. Tracking the grid allows the displacement estimation in the myocardium. The work described in this paper ...
متن کاملHolistic Image Reconstruction for Diffusion MRI
Diffusion MRI provides unique information on the microarchitecture of biological tissues. One of the major challenges is finding a balance between image resolution, acquisition duration, noise level and image artifacts. Recent methods tackle this challenge by performing super-resolution reconstruction in image space or in diffusion space, regularization of the image data or of postprocessed dat...
