Sur la génération de schémas d'échantillonnage compressé en IRM

Abstract : This article contains two contributions. First, we describe the state-of-the-art theories in compressed sensing for Magnetic Resonance Imaging (MRI). This allows us to bring out important principles that should guide the generation of sampling patterns. Second, we describe an original methodology to design efficient sampling schemes. It consists of projecting a sampling density on the space of feasible measures for MRI. We end up by proposing comparisons to current sampling strategies on simulated data. This illustrates the well-foundedness of our approach.
