Simultaneous Auto-calibration and Gradient Delays Estimation (SAGE) in non-Cartesian Parallel MRI using Low-rank Constraints
PURPOSE: To correct gradient timing delays in non-Cartesian MRI while simultaneously recovering corruption-free auto-calibration data for parallel imaging, without additional calibration scans. METHODS: The calibration matrix constructed from multi-channel k-space data should be inherently low-rank....
