Abstract: A system for monitoring a health status of a gradient coil disposed in a magnetic resonance imaging system is provided. The system includes one or more sensors and a controller. The one or more sensors are operative to obtain one or more parameter readings of the gradient coil, wherein the one or more parameter readings include at least one of an acoustic measurement and a back electromotive force measurement. The controller is in electronic communication with the one or more sensors and operative to generate the health status based on at least one of the acoustic measurement and the back electromotive force measurement.
