  • Patent number: 10921411
    Abstract: A combined dataset can be formed from partial datasets acquired at different positions of a patient support with a magnetic resonance device. The partial datasets can be of an anatomical region of a patient delimited perpendicularly to a longitudinal direction within an acquisition region. In a method for correcting the combined dataset formed from the partial datasets, for slices of a slice stack in the longitudinal direction of the combined dataset, information describing geometry of the anatomical region and/or an anatomical feature of the anatomical region is determined. For at least one slice group including adjacent slices, the geometry information is compared to detect one or more discontinuities. For at least one discontinuity of the one or more discontinuities satisfying a correction criterion, the combined dataset is corrected as a function of the geometry information to eliminate or reduce the at least one discontinuity.

  • Patent number: 10901061
    Abstract: Systems and methods for accelerated diffusion-weighted magnetic resonance imaging using a tilted reconstruction kernel to synthesize unsampled k-space data in phase encoded and point spread function (“PSF”) encoded k-space data are provided. Images reconstructed from the data have reduced B0-related distortions and reduced T2* blurring. In general, data are acquired with systematically optimized undersampling of the PSF and phase encoding subspace. Parallel imaging reconstruction is implemented with a B0 inhomogeneity informed approach to achieve greater than twenty-fold acceleration of the PSF encoding dimension. A tilted reconstruction kernel is used to exploit the correlations in the phase encoding-PSF encoding subspace. Self-navigated phase corrections are computed from the acquired data and used to synthesize the unsampled k-space data.
