Controlling sharpness, SNR and SAR for 3D FSE at 7T by end-to-end learning
Peter Dawood, Martin Blaimer, Jürgen Herrler +5
Purpose: To non-heuristically identify dedicated variable flip angle (VFA) schemes optimized for the point-spread function (PSF) and signal-to-noise ratio (SNR) of multiple tissues…
