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…
Characterization and Correction of Time-Varying Eddy Currents for Diffusion MRI
Jake J. Valsamis, Paul I. Dubovan, Corey A. Baron
Purpose: Diffusion MRI (dMRI) suffers from eddy currents induced by strong diffusion gradients, which introduce artefacts that can impair subsequent diffusion metric analysis. Exis…
