Abstract:
1. A magnetic resonance imaging apparatus comprising; an imaging means comprising a means for generating magnetic fields respectively of a static magnetic field, a gradient magnetic field, and an RF magnetic field, and a means for receiving an echo signal generated from a subject, the imaging means being for measuring echo data associated with at least one measurement trajectory in k-space, while varying angles of the measurement trajectory with respect to a coordinate axis in the k-space, so as to collect at least one measured data for each of the angles; and an image reconstruction means for rearranging the measured data in the k-space and reconstructing an image; wherein, the image reconstruction means further comprises a phase correction means for calculating a phase for correction based on standard data selected from the measured data for each of the angles, prior to rearranging the measured data in the k-space, and for performing a phase correction on the measured data, by using the calculated phase for correction.
