A multi-channel framework for joint reconstruction of multi-contrast parallel MRI
share
Compressed sensing, multi-contrast and parallel imaging are all techniques that exploit certain types of redundancies to speed up image acquisition process and image quality in MRI. Although each individual category has been well developed, the combination of the three has not received significant attention, much less the potential benefit of isotropy within such a setting. In this paper, a novel isotropic multi-channel image regularizer is introduced, and its full potential is unleashed by integrating it into compressed multi-contrast multi-coil MRI.
