Abstract
En 中文
Inductively coupled coils enhance local MRI sensitivity, yet strong coupling with nearby primary coils typically causes resonance splitting and impedance mismatch, which are traditionally considered detrimental. This work investigates why inductively coupled coils can still function effectively even in the presence of severe coupling and clarifies the role of modern receive preamplifiers in mitigating coupling effects.
