| 摘要 |
A magnetic resonance (MR) system comprising multiple radio-frequency (RP) coils (303) configured to apply an MR pulse sequence (100) including at least a preparation segment (PRP) and an acquisition segment (ACQ), wherein the preparation segment (PRP) and the acquisition segment (ACQ) each comprise one or more excitation pulses, is disclosed herein. The MR system further comprises a first control unit (308) configured to apply the one or more excitation pulses of the preparation segment (PRP) by activating the multiple radio -frequency coils in a first excitation pattern, and a second control unit configured to apply the one or more excitation pulses of the acquisition segment (ACQ) by activating the multiple radio-frequency coils in a second excitation pattern, thereby providing dynamic rf shimming. |
