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…

Recovery of damped exponentials using structured low rank matrix completion
Arvind Balachandrasekaran, Vincent Magnotta, Mathews Jacob
We introduce a structured low rank matrix completion algorithm to recover a series of images from their under-sampled measurements, where the signal along the parameter dimension a…

Novel Structured Low-rank algorithm to recover spatially smooth exponential image time series
Arvind Balachandrasekaran, Mathews Jacob
We propose a structured low rank matrix completion algorithm to recover a time series of images consisting of linear combination of exponential parameters at every pixel, from unde…
