SYSTEMS AND METHODS FOR IMPROVED RECONSTRUCTION OF MAGNETIC RESONANCE FINGERPRINTING DATA WITH LOW-RANK METHODS

摘要

Systems and methods for reconstructing MR parameter maps of a subject from magnetic resonance fingerprinting (MRF) data acquired using a magnetic resonance imaging (MRI) system. The method includes providing MRF data acquired from a subject using an MRI system and reconstructing the MRF data by solving a constrained optimization problem using a low-rank model, for which an input to the optimization problem is the MRF data and an output from the optimization problem is the MRF time-series images.
