Abstract: A device and method for detecting motion and position of a patient positioned within a magnetic resonance imaging system, the device including at least one sensor configured to be capacitively coupled to the patient during magnetic resonance imaging. The method includes, while a patient is positioned within a magnetic resonance imaging system, measuring a reflected power value indicative of an amount of power reflected by the at least one sensor in response to being driven by at least one RF signal, and determining, using the reflected power value, whether the patient has moved.
