MoDL-MUSSELS: Model-Based Deep Learning for Multi-Shot Sensitivity Encoded Diffusion MRI
Hemant Kumar Aggarwal, Merry P. Mani, Mathews Jacob
We introduce a model-based deep learning architecture termed MoDL-MUSSELS for the correction of phase errors in multishot diffusion-weighted echo-planar MRI images. The proposed al…
Calibration-free B0 correction of EPI data using structured low rank matrix recovery
Arvind Balachandrasekaran, Merry Mani, Mathews Jacob
We introduce a structured low rank algorithm for the calibration-free compensation of field inhomogeneity artifacts in Echo Planar Imaging (EPI) MRI data. We acquire the data using…
A General Algorithm For Compensation Of Trajectory Errors: Application To Radial Imaging
Merry Mani, Vincent Magnotta, Mathews Jacob
Purpose: To reconstruct artifact-free images from measured k-space data, when the actual k-space trajectory deviates from the nominal trajectory due to gradient imperfections. Meth…
