ITERATIVE ANALYSIS-BASED NON-CONVEX PRIOR FOR ENHANCED SPARSE RECOVERY

摘要

A system for performing non-convex signal recovery using magnetic resonance imaging data includes an imaging device and a central computer unit. The imaging device comprises a plurality of coils configured to acquire a k-space dataset acquired using a magnetic resonance imaging device. The central computer unit is configured to apply an iterative reconstruction process to generate an image based on the k-space dataset, wherein the iterative reconstruction process minimizes a cost function that uses a non-convex pseudo-norm applied to a tight frame combined with a data fitting term.
