Document Type and Number:
Japanese Patent JP4558866
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a phase distribution measuring method and an apparatus for efficiently determining an accurate phase map, a phase correcting method and an apparatus using the phase map determined in this way and a magnetic resonance image pickup apparatus for correcting such a phase. SOLUTION: A phase map of a reduced image of an original image is determined (902, 906), and this is enlarged to the phase map corresponding to the matrix size of the origonal image (910). A phase of the image is corrected by using the enlarged phase map (914), and a water-fat separated image is formed from the phase corrected image (916).
