1. A radio frequency (RF) receiver system for use in a magnetic resonance (MR) imaging system, the RF receiver system comprising:
at least one RF receive coil, the RF receive coil comprising at least one detune circuit, wherein the detune circuit comprising at least a pair of crossed diodes (D1, D2),
wherein the detune circuit further comprises an interface, wherein the interface is configured to measure an electrical direct current in the detune circuit to determine the proper function of the diodes (D1, D2) by measuring the detune direct current for a first detune voltage polarity and for a second reversed detune voltage polarity.
