| Zusammenfassung | Motivation: Flip angle variations or voids are problematic at 7T, especially when large fields of excitation are needed, such as for the entire abdomen. Goal(s): To homogeneously excite the whole abdomen using dynamic pTx and to investigate the minimal number of kT-points necessary. Approach: Dynamic pTx is applied in the abdomen using a 32-Tx-channel whole-body array and free-breathing relative B1+ mapping. Results: The preliminary data indicates that exciting the whole abdomen is feasible and that dynamic pTx yields sufficient FA homogeneity in all subjects. Impact: The preliminary data indicates that exciting the whole abdomen is feasible and that dynamic pTx yields sufficient FA homogeneity in all subjects.open hardware, parallel transmission, RF |
