  • Patent number: 10335049
    Abstract: Example 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. Sampling is performed in response to a fast imaging with steady state free precession (MRF-FISP) pulse sequence having an unbalanced gradient that dephases transverse magnetization. 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 unbalanced gradient in the MRF-FISP pulse sequence reduces sensitivity to B0 in homogeneity.
