← ScienceWhich risk dominates if insulation fails in MRI gradient coils?
A)Eddy current induced component heating
B)Cryostat helium quench occurrence risk✓
C)Imaging artifact resolution decreasing
D)Radio frequency interference increasing levels
💡 Explanation
Helium cryostats quench following insulation breakdown because uncontrolled current allows rapid energy deposition via Joule heating; therefore a quench dominates due to the thermal mechanism, rather than lower order effects like interference or artifacting.
