Current implementations of MR fingerprinting typically require over 1000 measurements to obtain the desired tissue maps. The large number entails an increased specific absorption rate and, to avoid excessive scan times, a subsampling of k-space that may incur undersampling artifacts. Here we propose an optimization method which allows reduction of the needed measurements ~100 fold without affecting image quality.
