System and method of compensation of radiofrequency spatial encoding misalignment errors due to gradient non-linearity in magnetic resonance imaging

A system and method for compensation of radiofrequency (RF) spatial encoding misalignment errors due to gradient non-linearity in magnetic resonance imaging is described. The true magnetic field produced by the gradient coils in space are taken into account in order to encode the appropriate frequency band and offset of the RF pulse corresponding to the desired spatial encoding position and thickness. This method is applicable to any positionally (frequency) encoded radiofrequency (RF) pulses including slice or slab excitation pulses, inversion pulses, spin echo (refocusing) pulses and spatial saturation pulses.
