Abstract

Systems and methods for magnetic resonance imaging acceleration are provided. The systems may perform the methods to obtain imaging data of a subject, or a portion thereof, captured by the MRI systemaccording to an under sampling pattern; execute a first iterative procedure; determine that the first iteration number meets a first threshold; execute, in response to the determination that the firstiteration number meets the first threshold, a second iterative procedure; determine that a sum of the first iteration number and the second iteration number meets a second threshold; and generate a reconstruction image of the subject, or a portion thereof, according to the processed imaging data, wherein the first threshold is lower than the second threshold.

Description

technical field [0001] The present disclosure relates generally to magnetic resonance imaging (MRI), and more particularly to methods and systems for magnetic resonance imaging acceleration. Background technique [0002] Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to obtain images of the anatomy and / or physiological processes of a subject in health or disease. To speed up MRI, a k-space undersampling mode can often be implemented, where data is sampled less frequently than Nyquist sampling theorem. Various k-space undersampling modes can reduce the quality of images reconstructed from k-space data acquired in this way, which in turn can interfere with diagnostics based on such images. It would be desirable to provide systems and methods that speed up magnetic resonance imaging with improved image quality. Contents of the invention [0003] A first aspect of the present disclosure relates to a system comprising: at least one non-trans...
