Abstract
A magnetic resonance imaging data sampling method includes randomly undersampling a first half of a k-space plane such that a plurality of points in the first half are sampled points and the remaining plurality of points in the first half are unsampled points. The method also includes determining, for each sampled point in the first half, a corresponding point in a second half of the k-space plane that corresponds to the point-wise complex conjugate location of the sampled point.
Claims20
A magnetic resonance imaging method, comprising:
- randomly undersampling a first portion of a k-space plane;
- computing, for each randomly undersampled point in the first portion of the k-space plane, a second point at a corresponding complex conjugate location in a second portion of a k-space sampling pattern corresponding to a second portion of the k-space plane;
- sampling additional points in either the first portion or the second portion of the k-space plane that have not been sampled or computed;
- and
- computing, for each additional sampled point, a corresponding point at a corresponding complex conjugate location.
A magnetic resonance imaging data sampling method, comprising:
- randomly undersampling a first half of a k-space plane such that a plurality of points in the first half are sampled points and the remaining plurality of points in the first half are unsampled points;
- and
- determining, for each sampled point in the first half, a corresponding point in a second half of a k-space sampling pattern that corresponds to the point-wise complex conjugate location of the sampled point.
A non-transitory computer readable medium encoding one or more executable routines, which, when executed by a processor, cause the processor to perform acts comprising:
- sampling magnetic resonance imaging data in an incoherent sampling pattern, wherein for each k-space location pair of points in a phase-encoding plane that are symmetric about an origin, one of the pair of points is sampled and the other of the pair of points is not sampled and is computed by using the complex conjugate of the sampled point.
