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.
