← ScienceWhich consequence results when localized magnetic fields exceed quenching limits in a clinical MRI?
A)Cryogen boil-off increases rapidly✓
B)Radiofrequency interference gets stronger
C)Image resolution enhances significantly
D)Gradient coil linearity stabilizes ideally
💡 Explanation
The quench occurs via positive feedback; strong fields can destabilize the superconducting magnet, leading to rapid normal state transition because resistive heating through electromagnetic induction causes further field collapse, therefore the cryogen rapidly boils off rather than signal errors.
