← ScienceDuring MRI operation, which effect limits image resolution?
A)Magnetic field inhomogeneity distorts signal
B)RF pulse bandwidth broadens resonance✓
C)Gradient coil inductance slows switching
D)Cryogen boil-off reduces field strength
💡 Explanation
Limited RF pulse bandwidth influences bandwidth of excitation frequencies due to Fourier Transform limit; therefore blurring increases, lowering the maximum resolution, rather than the magnetic field inhomogeneity which causes geometric distortions.
