METHOD FOR ACCURATE AND ROBUST CARDIAC MOTION SELF-GATING IN MAGNETIC RESONANCE IMAGING

摘要

Self-gating methods and Systems are provided for cardiac imaging analysis. In particular, non-phased coded self-gating data are collected separately from imaging data. The method uses multiple coil arrays to repeatedly acquire self-gating signals that are separate from image acquisitions. Learning-based algorithms are used in data processing to detect a triggering event, such as the onset of a heartbeat.

主权项

1. A method for synchronizing image data acquisition during Magnetic Resonance Imaging (MRI), comprising:
acquiring a self-gating dataset comprising a first plurality of subsets of self-gating data of the center k-space entire line, wherein the self-gating data are acquired separately from any imaging data, and wherein the first plurality of subsets of self-gating data is collected during the same cardiac cycle.
