Abstract:
A method of magnetic resonance imaging comprising the steps of:employing a magnetic resonance imaging apparatus having a plurality of gradient axes;employing a plurality of imaging planes with respect to said gradient axes;executing a plurality of gradient referencing pre-scans for said imaging planes to provide a plurality of calibration correction values for said imaging planes;employing a specimen with respect to said gradient axes;selecting an imaging plane with respect to the specimen;establishing a main magnetic field with respect to the specimen;applying radio frequency pulses to the specimen to produce magnetic resonance signals;employing said calibration correction values for the selected imaging plane to adjust a plurality of gradient waveforms;outputting said gradient waveforms as a plurality of magnetic field gradients with respect to said gradient axes;acquiring magnetic resonance information from the magnetic resonance signals corresponding to the radio frequency pulses; andemploying the magnetic resonance information and displaying an image of the specimen.
