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.
