Echo-Planar Spectroscopic Imaging (EPSI) reduces the long acquisition
time of Chemical Shift Imaging. “Flyback” trajectories sampling the lobe only
along one direction are commonly used for robustness and artifact reasons. Main
challenge in the design is that there is
no analytic solution for an SNR optimized readout/flyback
trapezoid pair. The goal of this work was to implement a fast SNR optimized
algorithm that takes Peripheral Nerve Stimulation into account to calculate
waveforms on the fly for any given spectral and spatial resolution and
therefore doesn’t require pre-calculated waveforms.
