Correction of B0 susceptibility induced distortion in diffusion-weighted images using large-deformation diffeomorphic metric mapping.
Geometric distortion caused by B0 inhomogeneity is one of the most important problems for diffusion-weighted images (DWI) using single-shot, echo planar imaging (SS-EPI). In this study, large-deformation, diffeomorphic metric mapping (LDDMM) algorithm has been tested for the correction of geometric distortion in diffusion tensor images (DTI). Based on data from nine normal subjects, the amount ...
متن کاملCorrection of B0 induced slice profile distortion using parallel transmit
Introduction: With the advent of parallel transmit (PTx), there has been much interest in creating complex spatially localised excitations. The algorithms which calculate the requisite pulses [1,2] require an estimate of the B1 field produced by each coil, and also a map of the B0 (off resonance) field, since this distorts the excited magnetisation profiles. In fact spatially localized excitati...
متن کاملDistortion correction and robust tensor estimation for MR diffusion imaging
This paper presents a new procedure to estimate the diffusion tensor from a sequence of diffusion-weighted images. The first step of this procedure consists of the correction of the distortions usually induced by eddy-current related to the large diffusion-sensitizing gradients. This correction algorithm relies on the maximization of mutual information to estimate the three parameters of a geom...
متن کاملDiffusion tensor imaging distortion correction with T 1
Introduction Diffusion weighted single shot spin-echo planer imaging (DW-EPI) is commonly used for diffusion tensor imaging (DTI). DW-EPI is very sensitive to static magnetic field (B0) inhomogeneities (such as that near air-tissue boundary) that produce geometric distortion, primarily along the phase-encoding direction. As a result, artifacts are severe in the frontal and temporal lobes due to...
متن کاملComparison of EPI Distortion Correction Methods in Diffusion Tensor MRI
Introduction Diffusion weighted images (DWIs) used for Diffusion Tensor (DT) calculation are commonly acquired with Echo-planar imaging (EPI). Unfortunately, EPI is very sensitive to magnetic field (B0 ) inhomogeneities, which result in local geometric distortions in regions close to air-tissue interfaces. These distortions degrade the anatomical accuracy of DT-MRI maps and potentially increase...
