← ScienceWhich risk increases when pulsed electromagnetic fields exceed tolerance in MRI machines?
A)Quench-induced high cryogenic temperatures
B)Eddy current heating of tissues✓
C)Superconducting magnet demagnetization
D)Degradation of RF coil shielding
💡 Explanation
Overly strong or rapid pulsed electromagnetic fields induces increased ion currents, therefore eddy current cause disruptive and potentially unsafe dielectric cellular heating, rather than problems with quenching or magnetic field alignment itself or coil degradation since the coil will dissipate generated voltage.
