The application of respiratory gating for MRI with continuously moving table is difficult. Due to the variability of the breathing motion over time the coverage of the complete k-space in the available measurement time which is fixed by the table motion cannot be guaranteed. In this study a variant of respiratory gating is proposed that acquires the required k-space data in a limited time as consistently as possible with respect to motion. Compared to acquisitions without motion correction blurring artifacts are reduced thereby significantly improving the diagnostic image quality.
