摘要
In a method for image data acquisition using a magnetic resonance system, in order to excite nuclear spin signals, a sequence of high-frequency pulses is irradiated into an examination subject while gradients are simultaneously switched for position encoding of the excited nuclear spin signals. The rise times of the gradients used during the sequence are adjusted dynamically with each high-frequency pulse irradiation.
