| Zusammenfassung | Respiratory motion during data acquisition can introduce strong motion artefacts in 2D cine cardiac MR images. The commonly used breathhold method minimizes these artefacts, but also limits achievable image resolution and requires patient cooperation. Here we present a prospective motion correction technique using RF pilot tone signals with high temporal resolution. A calibration scan was carried out to convert signal intensity changes of the pilot tone to displacements of the heart due to breathing. The proposed approach was evaluated in four healthy volunteers and allowed for free-breathing 2D cine MR with high image quality. |
