In an apparatus and method for correction of DC offset in magnetic resonance imaging signals, a phase-alternated RF pulse sequence causes the resulting DC offset artifact to be positioned at the boundaries of the object image, rather than at its center. The resulting artifact may be corrected by pre-calculating the region of the image data affected by the DC offsets, and by using the estimated errors in the image data to correct the collected data prior to image reconstruction. <IMAGE> |
