Claim 0:
1. A method for determining an undersampling error for a magnetic resonance fingerprinting (MRF) pulse sequence, the method comprising:
retrieving, from data storage, a plurality of sets of spatial response functions, wherein each set of spatial response functions is associated with a tissue type in a region of interest of a reference image and each set of spatial response functions is based on a tissue mask of the reference image associated with the tissue type corresponding to the set of spatial response functions;
generating a plurality of signal evolutions based at least on the MRF pulse sequence, each of the plurality of signal evolutions associated with a tissue type for the region of interest in the reference image;
generating an undersampled image for each tissue type using the set of spatial response functions for the tissue type and the signal evolutions for the tissue type;
combining the undersampled image for each tissue type to create an undersampled image series;
comparing the undersampled image series to an MRF dictionary to determine at least one quantitative parameter;
generating a quantitative map for the at least one quantitative parameter; and
generating an undersampling error for the MRF pulse sequence by comparing the quantitative map and the reference image.
