Correction of high-order phase variation effects in dynamic field monitoring

Paul I. Dubovan, Kyle M. Gilbert, Corey A. Baron

Purpose: Field monitoring measures field perturbations, which can be accounted for during image reconstructions. In certain field monitoring environments, significant phase deviati…

High-resolution single-shot spiral diffusion-weighted imaging at 7T using expanded encoding with compressed sensing

Gabriel Varela-Mattatall, Paul I. Dubovan, Tales Santini +3

Purpose: The expanded encoding model incorporates spatially- and time-varying field perturbations for correction during reconstruction. So far, these reconstructions have used the…

Model-based determination of the synchronization delay between MRI and trajectory data

Paul I. Dubovan, Corey A. Baron

Purpose: Real time monitoring of dynamic magnetic fields has recently become a commercially available option for measuring MRI k-space trajectories and magnetic fields induced by e…

Tuned bipolar oscillating gradients for mapping frequency dispersion of diffusion kurtosis in the human brain

Kevin B. Borsos, Desmond H. Y. Tse, Paul I. Dubovan +1

Purpose: Oscillating gradient spin echo (OGSE) sequences have demonstrated an ability to probe time-dependent microstructural features, though they often suffer from low SNR due to…

Least Squares Optimal Density Compensation for the Gridding Non-uniform Discrete Fourier Transform

Nicholas Dwork, Daniel O'Connor, Ethan M. I. Johnson +4

The Gridding algorithm has shown great utility for reconstructing images from non-uniformly spaced samples in the Fourier domain in several imaging modalities. Due to the non-unifo…

BMART-Enabled Field-Map Combination of Projection-Reconstruction Phase-Cycled SSFP Cardiac Cine for Banding and Flow-Artifact Reduction

Anjali Datta, Dwight G Nishimura, Corey A Baron

Purpose: To develop a method for banding-free bSSFP cardiac cine with substantially reduced flow artifacts. Methods: A projection-reconstruction (PR) trajectory is proposed for a f…
