Self‐calibrated trajectory estimation and signal correction method for robust radial imaging using GRAPPA operator gridding

A Deshmane, M Blaimer, F Breuer… - Magnetic resonance …, 2016 - Wiley Online Library
Purpose In radial imaging, projections may become “miscentered” due to gradient errors
such as delays and eddy currents. These errors may result in image artifacts and can disrupt …

Trajectory auto‐corrected image reconstruction

JD Ianni, WA Grissom - Magnetic resonance in medicine, 2016 - Wiley Online Library
Purpose To estimate k‐space trajectory errors in non‐Cartesian acquisitions and reconstruct
distortion‐free images, without trajectory measurements or gradient calibrations. Theory and …
