1. A system, comprising:
a sensor operative to obtain a parameter reading of a gradient coil disposed in a magnetic resonance imaging system, wherein the parameter reading includes a back electromotive force (back EMF) measurement induced by movement of the gradient coil within a magnetic field provided by the magnetic resonance imaging system; and
a controller configured to obtain the back EMF measurement from the sensor and evaluate the structural integrity of the gradient coil as a function of the back EMF measurement; and
a memory device storing a set of rules defining acceptance criteria for back EMF measurements obtained from the gradient coil that are indicative of a structurally sound gradient coil;
wherein the controller is configured to report a status of the structural integrity of the gradient coil to a system user.
