ASL fingerprinting. A pseudo-random labeling scheme is used to generate an image time series whose signal is unique for a given combination of hemodynamic parameters. The top panel indicates a labeling function, the second panel shows the concentration of the label in the arterial compartment. Similarly, the third panel shows the concentration of the label in the extra-vascular compartment. The total magnetization (spin history) of the whole voxel is plotted in the fourth compartment. Finally, the bottom panel shows the observed time series from two different voxels.
