Abstract
A transient noise detection system includes an imaging system having a magnetic field coil and an imaging bore. The imaging system generates an imaging signal through a signal cable, wherein the imaging signal is corruptible by a noise event. A noise event detector is positioned outside of the imaging bore and proximate to the signal cable. This detector detects the noise event from the signal cable and generates a noise signal therefrom.
