Abstract
In a method and a magnetic resonance apparatus for generating movement information relating to an examination region of a patient, a reception circuit is provided that receives MR signals within a reception frequency range. An electromagnetic signal is generated that has a first frequency that is outside the reception frequency range of the reception circuit, and that interacts with at least some of the examination region, so the electromagnetic signal undergoes a modification. A modulated signal based on the modified first signal is generated that has a frequency within the reception frequency range. The modulated signal is transmitted to the reception circuit, and is forwarded to a computer, wherein movement information is determined based on the modulated signal.
