Abstract:
Apparatus, methods, and other embodiments associated with NMR fingerprinting are described. One example NMR apparatus includes an NMR logic that repetitively and variably samples a (k, t, E) space associated with an object to acquire a set of NMR signals that are associated with different points in the (k, t, E) space. Sampling is performed with t and/or E varying in a non-constant way. The NMR apparatus may also include a signal logic that produces an NMR signal evolution from the NMR signals, and a characterization logic that characterizes a resonant species in the object as a result of comparing acquired signals to reference signals. The NMR signal evolution may be assigned to a cluster based on the characterization of the resonant species. Cluster overlay maps may be produced simultaneously based, at least in part, on the clustering. The clusters may be associated with different tissue types.

Claim (Index 1):
A method, comprising:\n accessing a set of known signal evolutions; accessing an acquired nuclear magnetic resonance (NMR) signal, where the acquired NMR signal is acquired from a volume that contains one or more resonant species that simultaneously produced individual NMR signals in response to magnetic resonance fingerprinting (MRF) excitation; finding a selected entry in the set of known signals that matches the acquired NMR signal; identifying one or more magnetic resonance (MR) parameters for the volume based on stored MR parameters associated with the selected entry, where the one or more MR parameters include T1 relaxation associated with the resonant species, T2 relaxation associated with the resonant species, off-resonance relaxation associated with the resonant species, and diffusion weighted relaxation associated with the resonant species, T1 being spin-lattice relaxation, T2 being spin-spin relaxation, and assigning the volume that produced the acquired NMR signal to a cluster in a plurality of clusters based on the one or more MR parameters.
