| description | A magnetic resonance imaging (MRI) system (600) for obtaining magnetic resonance (MR) images of a volume. The MRI system may include at least one controller(610) which may be configured to perform a preparation scan (103, 301) to acquire preparation echo phase information (105, PEPI) for a plurality of dynamics of a scan (300); output a plurality of pulse sequences (200) each of which is configured for a corresponding dynamic of the plurality of dynamics of the scan and comprises a navigator sequence (204) and an image sequence (206); acquire navigation and image information (111, 117) for each corresponding pulse sequence of the plurality of pulse sequences; and/or form corrected image information (125) by correcting echo phase information of the image information in accordance with the preparation echo phase information, correcting at least one of gradient delay and frequency offset of the image information in accordance with the navigation information. |
