Figure 6.
Vessel-selective labeling schemes. The left panel shows a vessel-encoded labeling pattern that labels specific groups of arteries. The in-plane gradients generate a linear phase variation along the gradient direction, resulting in an approximately sinusoidal inversion profile across the label plane. The individual perfusion territories are then calculated by either solving a set of linear equations or by using a clustering approach. The right panel shows a schematic of the super-selective labeling scheme, which can isolate individual arteries by rotating the “labeling band” during the pseudo continuous labeling train of pulses.
