1. A method of acquiring spatially encoded magnetic resonance (MR) data comprising the steps of:
applying a gradient field having an exponential relation higher than a single order along an object direction;
moving an object to be scanned in the object direction through the gradient field; and
acquiring MR data as the object moves with contiguous continuity in the object direction.
