Abstract :
A class of methods of MR image intensity correction extracts the sensitivity map from the image. This usually causes the edge enhancement artifact in the corrected image. A novel method of extrapolating the image in advance is proposed to reduce this effect significantly. The closest point algorithm is used to perform extrapolation
