Abstract
In an MRI system, a region including a portion of interest is selectively excited in a predetermined pulse sequence to acquire 3 dimensional MR data. When the portion of interest is shifted from the center position of imaging, i.e., the center position of a gradient field, the 3 dimensional MR data is phase-corrected in accordance with the shift. The phase-corrected 3 dimensional MR data is 3-dimensional Fourier-transformed to obtain an MR image of a predetermined slice portion.
