Abstract
A magnetic resonance (MR) imaging acceleration method is provided. The method includes applying, by an MR system, a pulse sequence having a k-space trajectory of a plurality of blades being rotated in k-space, each blade including a plurality of views, wherein the k-space trajectory has an undersampling pattern in the k-space. The method also includes receiving k-space data of a subject acquired by the pulse sequence, reconstructing MR images of the subject based on the k-space data using compressed sensing, and outputting the reconstructed images.

A magnetic resonance (MR) imaging acceleration method, comprising:
- applying, by an MR system, a pulse sequence having a k-space trajectory of a plurality of blades being rotated ink-space, each blade including a plurality of views, wherein the k-space trajectory has an undersampling pattern in the k-space, wherein applying a pulse sequence further comprises:
- reducing a number of views in a blade in a view undersampling pattern while maintaining a size of the blade;
- receiving k-space data of a subject acquired by the pulse sequence;
- reconstructing MR images of the subject based on the k-space data using compressed sensing;
- and
- outputting the reconstructed images.
A magnetic resonance (MR) imaging acceleration system, comprising an imaging acceleration computing device, the imaging acceleration computing device comprising at least one processor in communication with at least one memory device, and the at least one processor programmed to:
- receive k-space data of a subject acquired by a pulse sequence having a k-space trajectory of a plurality of blades being rotated in k-space, each blade including a plurality of views, wherein the k-space trajectory has an undersampling pattern, wherein in the pulse sequence, a number of views in a blade is reduced in a view undersampling pattern while maintaining a size of the blade;
- reconstruct MR images of the subject based on the k-space data using compressed sensing;
- and
- output the reconstructed images.
