The Paradox of Radial MRI: When Repeated Sampling of K‐Space Center Becomes a Double‐Edged Sword

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Radial MRI has been extensively investigated for decades and has become one of the most widely studied non‐Cartesian sampling schemes in MRI research. Major advances in image reconstruction, free‐breathing imaging, and highly‐accelerated MRI have further expanded interest in radial acquisition.

Fast Reconstruction of Motion‐Corrupted Data With Mobile‐GRAPPA: Motion and δB0$$ \delta {B}_0 $$ Inhomogeneity Correction Leveraging Efficient GRAPPA

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an accurate and computationally efficient motion‐corrected MRI reconstruction framework that incorporates hundreds to thousands of motion and δB0$$ \delta {B}_0 $$ estimates from high‐temporal‐resolution tracking. Methods We propose Mobile‐GRAPPA, a k‐space preprocessing approach that uses MLP‐parameterized local GRAPPA ...

Ghost image removal using physical layer spatial asymmetry in frequency-diverse computational imaging

, 2021
Ghost images are one of the undesired artifacts in an imaging system besides a real image. It also happens in frequency-diverse computational imaging used to reduce the complexity of traditional imaging systems using a mechanical scan or active circuits.
