Abstract
Techniques, systems and apparatus are described for magnetic resonance imaging by modifying the shape/thickness of an excitation/inversion slab. For instance, the inversion slab can be shaped as a wedge to improve temporal signal-to-noise ratio (tSNR) of arterial spin labeling (ASL) experiments by matching the temporal bolus width with the inter-pulse spacing in different feeding arteries. The shape/thickness of the excitation/inversion slab across the X-Y plane can be modified by modulating the movement of the 'on-resonance' plane in space by the combination of conventional slice-selective (SS) adiabatic fast passage (AFP) and additional in-plane gradient pulses. Using this method, a computer can generate different shapes of the excitation/inversion slab.
