According to a method for characterizing a motion of an object, a reference signal is emitted into a target region and two or more receiver coil signals are generated in response to the reference signal by two or more receiver coils. A motion signal characterizing a motion of the object is determined by a computing unit depending on temporal modulations of the two or more receiver coil signals. A correlation coefficient of the motion signal and a receiver coil signal is computed by the computing unit. A reference correlation coefficient is determined by the computing unit depending on a location of the receiver coil based on a predetermined reference correlation map. The motion signal is corrected by the computing unit depending on a correlation coefficient and the reference correlation coefficient.

Characterizing a motion of an object

A pilot tone signal generator, a magnetic resonance tomograph, a method for transmission of a synchronization signal, and a computer program product are disclosed. The pilot tone signal generator includes a receive unit for receipt of a synchronization signal of a system control unit of a magnetic resonance tomograph. The synchronization signal may include a clock signal, and the pilot tone signal generator is configured to emit a pilot tone signal as a function of the synchronization signal.
