| 摘要 |
A method and a control sequence determination device for determining a magnetic resonance system control sequence is disclosed. The magnetic resonance system control sequence includes a multi-channel pulse with a plurality of individual high-frequency (HF) pulses to be transmitted in parallel by the magnetic resonance system via different independent high-frequency transmission channels. In one embodiment, the method includes calculating a multi-channel pulse based on an MR excitation quality parameter in an HF pulse optimization method. An HF pulse includes a plurality of successive HF partial pulses in discrete time steps. The method further includes considering, in the course of the HF pulse optimization method, a transmission bandwidth of an HF partial pulse to be transmitted during a discrete time step. A method for operating a magnetic resonance system and a magnetic resonance system that includes the control sequence determination device are disclosed. |
