Compressed Sensing in MRI

Michael Lustig¹

Compressed sensing is a technique that can be used to significantly accelerate the acquisition of MR Imaging. It exploits the fact that medical images, much like natural images taken with digital cameras can be compressed many folds. This is information is used to reconstruct images from vastly undersampled data. In recent years, Compressed sensing has been gaining much interest in the field of MR. This talk will provide an overview of the basics behind compressed sensing in the context of MR imaging, and review the current status and trends in clinical applications.
