Impedance and Q-value of a MRI coil is dependent on its loading. Load changes due to motion can be measured by recording of the impedance change. In this work, we show, that on different positions of the body, respiratory and myocardial motion signals as well as flow profiles can be acquired by impedance change measurement and pulse wave velocity can be calculated. This additional physiological information could be acquired during the MRI examination. This technique has potential for sensor-less measurement of physiological data and motion for gating or triggering purposes, especially in environments where classical sensors do not perform well.
