PROBLEM TO BE SOLVED: To perform MR imaging of a large-size FOV (field-of-view) by correcting non-linearity of a gradient magnetic field. SOLUTION: The gradient non-linearity correction is applied to a stretcher type imaging desired to have a single range magnified image, collects MR data accompanied with motion under the presence of the gradient non-linearity, converts the collected MR data into the image range, and applies a warp correction function to the converted MR data. The warp corrected MR data is corrected on the motion guided during the MR collection. The data may be collected for every points, every lines, or using another small part to the collected whole MR data as a unit. The data may be processed to minimize the amount of the necessitating motion correction. COPYRIGHT: (C)2004,JPO
