The disclosure relates to a magnetic resonance imaging device configured to exert a high-frequency electromagnetic field on an object under test in a static magnetic field and to reconstruct an image based on magnetic resonance signals. The magnetic resonance imaging device comprises a receiving coil comprising a plurality of receiving coil elements and configured to receive magnetic resonance signals and feed the magnetic resonance signals to a receiver, and a coupler configured to be coupled with at least a first receiving coil element of the receiving coil, the coupler being directionally coupled with at least the receiver, the first receiving coil element being configured to receive a high-frequency electromagnetic wave signal through the coupler. The directional coupling between the coupler and the receiver is so regulated that the first receiving coil element transmits the high-frequency electromagnetic wave signal to the object under test to sense a physiological movement signal.
