IMPROVEMENT IN MAGNETIC RESONANCE IMAGING RELATING TO CORRECTION OF CHEMICAL SHIFT ARTIFACT AND INTENSITY INHOMOGENEITY
摘要
Present invention discloses systems and methods for improvement of magnetic resonance images. Correction of a chemical shift artefact in an image acquired from a magnetic resonance imaging system is obtained by a system and a method involving iterative - compensation for the misregistration effect in an image domain. Correction of an intensity inhomogeneity in such images is obtained by a system and a method involving locating voxels corresponding to pure adipose tissue and estimating correction field from these points.
