چکیده
Table 1. A comparison of valid tensors in the DTIs based on DWIs of different strategies of distortion correction. Our method provided the best result, while some other method may increase the number of ill-conditioned tensors (nonpositive definite). (a) (b) (c) (d) Figure 1. A comparison of distortion correction using different approaches. First Row: The simulated dataset; Second Row: The real dataset. (a)Reference image; (b)Distorted image (M,T,S were 0.9,0.2,-0.08 respectively); (c)Correction of (b) using ICC; (d) Correction of (b) using our proposed. The red rectangles indicate visually notable differences. A NOVEL ALGORITHM FOR THE CORRECTION OF EDDY CURRENT DISTORTION IN DIFFUSION

PURPOSE To correct distortions caused by eddy currents induced by large diffusion gradients during high angular resolution diffusion imaging without any auxiliary reference scans. MATERIALS AND METHODS Image distortion parameters were obtained by image coregistration, performed only between diffusion-weighted images with close diffusion gradient orientations. A linear model that describes dis...
متن کاملComprehensive approach for correction of motion and distortion in diffusion-weighted MRI.
Patient motion and image distortion induced by eddy currents cause artifacts in maps of diffusion parameters computed from diffusion-weighted (DW) images. A novel and comprehensive approach to correct for spatial misalignment of DW imaging (DWI) volumes acquired with different strengths and orientations of the diffusion sensitizing gradients is presented. This approach uses a mutual information...
متن کاملFieldmap-Free Retrospective Registration and Distortion Correction for EPI-based Diffusion-Weighted Imaging
Introduction Acquisition of a set Diffusion Weighted Images (DWIs) allows Diffusion Tensors and Tensor-derived quantities such as Fractional Anisotropy (FA) and Trace (TR) to be computed and used to infer the underlying white matter structure in the brain. DWIs are usually acquired with an echo-planar imaging (EPI) pulse sequence that produces images degraded by B0 field inhomogeneity, eddy cur...
متن کاملThe eddy current distortion in the multiband diffusion images: diagnosis and correction
The diffusion weighted images acquired with the multiband sequence or the Lifespan protocols shows a type of slice distortion artifact. We find that this artifact is caused by the eddy currents, which can be induced by the diffusion gradient associated with either current DW image or the previous DW images. The artifact can be corrected by further tuning the compensation circuit in the MR hardw...
