Laterally Oscillating Trajectory for Undersampling Slices: LOTUS

Mayuri Sothynathan, Paul I. Dubovan, Corey. A. Baron

Purpose: While spiral sampling offers SNR advantages for diffusion MRI, its acceleration with simultaneous multislice remains relatively unexplored. This study introduces Laterally…

Basis function compression for field probe monitoring

Paul Dubovan, Gabriel Varela-Mattatall, Eric Michael +5

Purpose: Field monitoring using field probes allows for accurate measurement of magnetic field perturbations, such as from eddy currents, during MRI scanning. However, errors may r…

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…

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…

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…
