The researcher or engineer who is working with nonlinear gradient fields is addressed. Maybe the most challenging problem with multi-dimensional trajectories is that they tend to be extremely sensitive to calibration errors. In this abstract a band-shaped artifact that may result from miscalibration is investigated and explained. The analysis reveals how such an artifact can be avoided when designing new multi-dimensional encoding schemes.
