Title:
画像における動きの影響を低減する方法および装置
Document Type and Number:
Japanese Patent JP3976684
Kind Code:
B2
Abstract:
A method and apparatus for reducing the effects of motion of a subject during image acquisition is presented. The method is particularly suitable for correcting the motion during magnetic resonance imaging. The method involves comparing an image with a reference image in the spatial frequency domain to determine the extent of any rotational and/or translational motion and then apply an appropriate correction. Any motion is modeled by comparison with the reference image but the corrected image is produced using information from the corrupted image alone.
