摘要:
In a method and magnetic resonance (MR) apparatus for determination of movement of an examination subject during the acquisition of (MR) measurement data using at least two antenna elements that exhibit respectively different spatial positions, after each radiated excitation pulse a navigator signal is acquired in the measurement data and movement of the examination subject between two excitation pulses during the acquisition of the measurement data is determined from a change of the signal strength of the navigator signal in the at least two antenna elements and based on the respective spatial positions of the antenna elements.
