← ScienceWhich effect results when an MRI RF amplifier limit triggers?
A)Spatial resolution decreases significantly✓
B)Magnetic field strength fluctuates wildly
C)Cryogen quench happens immediately
D)Patient table locks prevent movement
💡 Explanation
Reduced power causes inadequate gradient coil driving preventing full k-space data acquisition during resonant excitation because the amplifier clips. Therefore, spatial definition is lost, rather than mechanical failure or complete quenching, due to insufficient power to image reconstruction kernels.
