Previously, we showed that compressive or compressed sensing (CS) can be used to
reduce significantly the data required to obtain 2D-NMR relaxation and diffusion spectra
when they are sparse or well localized. In some cases, an order of magnitude fewer
uniformly sampled data were required to reconstruct 2D-MR spectra of comparable quality.
Nonetheless, this acceleration may still not be sufficient to make 2D-MR spectroscopy
practicable for many important applications, such as studying time-varying exchange …
