Correction of Gradient Nonlinearity Artifacts in Prospective Motion Correction for 7T MRI

PURPOSE: To demonstrate the effect of gradient nonlinearity and develop a method for correction of gradient non-linearity artifacts in prospective motion correction (Mo-Co). METHODS: Non-linear gradients can induce geometric distortions in MRI, leading to pixel shifts with errors of up to several mi...
