Variable density band-based undersampling scheme for Compressed Sensing MRI reconstruction

Nicolás F. Sánchez, Juan José Rojas, Juan Carlos Cabral, Christian E. Schaerer

Resumo


Magnetic resonance of brain images have an implicit sparsity in an appropriate transformdomain [1]. Based on compressed sensing theory (CS), images with a sparse representation can berecovered from undersampledk-space data. However, to have an efficient reconstruction [1], theundersampling scheme should be incoherent with respect to the sparsifying transform [2]. [...]
