The present invention provides a magnetic resonance imaging (MRI) system 100 including a memory 134 for storing machine executable instructions 140 and MRF pulse sequence commands 142. The MRF pulse sequence command causes the MRI system to acquire MRF magnetic resonance data 144 according to a magnetic resonance (MR) fingerprinting protocol. The pulse sequence command is configured to acquire MRF magnetic resonance data of the two-dimensional slices 410, 412, 414, 416, 418, 420, the two-dimensional slice has a slice selection direction, and the pulse sequence command has a pulse sequence repeat Including the train. The train of pulse sequence repetitions includes sample events where the MRF magnetic resonance data is repeatedly sampled. The MRI system further comprises a processor for controlling the magnetic resonance imaging system. Execution of the machine-executable instructions causes the processor to acquire MRF magnetic resonance data by controlling the magnetic resonance imaging system with MRF pulse sequence commands (200) and to use the MRF magnetic resonance data to scan a two-dimensional slice. Configuring (202) at least one series of magnetic resonance parameter values 148 for each voxel, each of the series of magnetic resonance parameter values corresponding to a sampling event of each pulse sequence repetition (202). And a composition 502, 504, 506, 508 for each of the set of predetermined substances in the two or more subvoxels 306, 308 of each voxel of the two-dimensional slice, and a subvoxel magnetic resonance for each of the two or more subvoxels. Calculating (204) using the fingerprinting dictionary 150 and at least one series of magnetic resonance parameter values, the subvoxels dividing each voxel in a slice selection direction (204).
