- 摘要：
PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus that corrects the body movements of a subject.
SOLUTION: In the step S1, displacement quantities &Deltax (u
k , x, y) and &Deltay (uk , x, y) are calculated based on the data obtained by the tagging sequence TS1 to TSA of training scanning. In the step S2, displacement quantities &Deltax (un , x, y) and &Deltay (un , x, y) at the encoding of the phase of n times are calculated based on the position of the diaphragm obtained by the navigator sequence NV of the present scanning. In the step S3, the image data f (x, y) are calculated based on the displacement quantities &Deltax (un , x, y) and &Deltay (un , x, y) calculated in the step S2, and the data S (t, n) of space k obtained by the imaging sequence of the present scanning.COPYRIGHT: (C)2011,JPO&INPIT
