Left–right (LR) distortion maps for the 3D phantom in the transverse plane. (Left) Quantified gradient nonlinearity distortion for the 3D phantom at 15 cm inferior of isocenter. (Right) Residual distortion after postprocessing corrections were applied. Results for the entire volume can be observed in Multimedia view.
