Abstract
The following relates generally to ensuring patient safety while operating a Magnetic Resonance Imaging (MRI) machine. Many MRI systems operate using: fiber optic cables to carry signals, electrically conductive cables to carry other signals, and radio frequency (RF) coils to create an electromagnetic field. Typically, the electrically conductive cables and RF coils do not interact in a way that causes harm to a patient. However, certain shapes and/or lengths of cables exhibit the phenomenon of 'resonance' that increases their propensity to concentrate RF currents induced by the RF coils. This may increase the temperature of the cable or other component in the MRI system leading to patient harm. The methods disclosed herein provide a solution to this by sensing a shape of the fiber optic cable and determining if the fiber optic cable will exhibit resonance. If it is determined that resonance may potentially occur, an alarm may be generated or a radio frequency amplifier may be interlocked.
