  • MRI tomography apparatus for generating a motion signal
    Patent number: 4694836
    Abstract: A method of generating a motion signal which is dependent on motion of a body to be examined in an MRI tomography apparatus, characterized in that during the examination the impedance of a high-frequency coil system (33; 34) whose field acts on the body (3) to be examined and which is tuned to a predetermined resonance frequency is measured in the resonance frequency range with the motion signal being derived from the measurement signal just formed.
