Figure 4

Color-coded, magnitude displacement error of the fiducial phantom MRI reconstruction compared to the CT-measured ground truth positions for a 500 mm DSV across three different model orders used for gradient nonlinearity correction. Note the improved spatial accuracy moving from 5th to 7th, then to 9th order corrections. Reported in the inset are the RMSE and maximum error of the dataset.
