Enhancing Resolution in Undersampled Physical Imaging

Robert Calderbank

Duke University, USA   -

Compressed sensing MRI was first proposed by Lustig and Donoho, and it is now starting to appear in commercial systems. Candes, Tao and Romberg used Incoherence between measurements and representations of signals to develop performance guarantees for compressed sensing. We demonstrate here that fidelity and resolution in physical imaging systems can be improved by taking advantage of shared asymptotic characteristics of signals and measurement devices. We present new experimental results, explaining why and how improvements are possible.
