1. A method for ascertaining an item of movement information concerning movement of an object under examination during a magnetic resonance scan, the method comprising:
transmitting a pilot tone signal by a pilot tone signal generator of a magnetic resonance apparatus;
receiving the pilot tone signal by at least one first coil element of the magnetic resonance apparatus as an at least one first pilot tone received signal;
receiving the pilot tone signal by at least one second coil element of the magnetic resonance apparatus as an at least one second pilot tone received signal;
correcting the first pilot tone received signal with the at least one second pilot tone received signal; and
ascertaining an item of movement information for the object under examination using the corrected at least one first pilot tone received signal.
