Abstract
Methods, apparatus, and other embodiments associated with producing a quantitative parameter map using magnetic resonance fingerprinting (MRF) are described. One example apparatus includes a data store that stores a grouped set of MRF signal evolutions, including a group representative signal and a low-rank representative, a set of logics that collects a received signal evolution from a tissue experiencing nuclear magnetic resonance (NMR) in response to an MRF excitation, a correlation logic that computes a correlation between a portion of the received signal evolution and a portion of a group representative signal, a pruning logic that generates a pruned grouped set, and a matching logic that determines matching quantitative parameters based on the received signal evolution and the low-rank representative.
