A new method to perform a multi-component analysis in MR Fingerprinting is proposed, which is faster and less sensitive to noise than previous methods. The algorithm finds a small number of components throughout the region of interest without assumptions about the number or relaxation times of the components. The proposed method is compared to previously published methods in numerical simulations and in vivo experiments.
