The invention provides a method of magnetic resonance imaging. A magnetic resonance imaging apparatus having a plurality of gradient axes is employed. A plurality of imaging planes are employed with respect to the gradient axes. A plurality of gradient referencing pre-scans are executed for the imaging planes to provide a plurality of calibration correction values for the imaging planes. A specimen is employed with respect to the gradient axes. An imaging plane is selected with respect to the specimen, and a main magnetic field is established with respect to the specimen. Radio frequency pulses are applied to the specimen to produce magnetic resonance signals. The calibration correction values for the selected imaging plane are employed to adjust a plurality of gradient waveforms. The gradient waveforms are output as a plurality of magnetic field gradients with respect to the gradient axes. Magnetic resonance information is acquired from the magnetic resonance signals corresponding to the radio frequency pulses. The magnetic resonance information is employed to display an image of the specimen. Associated apparatus and calibration method are also disclosed.
