Abstract:
Efficient gradient cable monitoring is enabled by a device and a method to determine a failure in at least one gradient coil of a magnetic resonance tomography system with gradient cables supplying current thereto, wherein the difference of at least one electrical current flowing through a gradient cable to a gradient coil and at least one electrical current flowing through a gradient cable away from a gradient coil is determined. A failure of a gradient cable is assumed if the absolute value of the difference exceeds a limit value.
