Radio frequency receiver with detection of a malfunction of a detune circuit

Abstract

For a radio frequency (RF) receiver system a solution for a safe operation of the radio frequency (RF) receiver system in magnetic resonance imaging shall be ensured. This is achieved by a radio frequency (RF) receiver system for use in a magnetic resonance (MR) imaging system the RF receiver system, wherein the RF receiver system comprises at least one RF receive coil with at least one detune circuit (1). The detune circuit (1) comprises at least a pair of crossed diodes (D1, D2) with an interface, wherein the interface is configured to measure an electrical current in the detune circuit (1) to determine the proper function of the PIN diodes (D1, D2) by measuring the detune direct current for a first detune voltage polarity and for a second reversed detune voltage polarity. The present invention also provides a magnetic resonance (MR) imaging system, a method for ensuring a safe radio frequency (RF) receiver system operation in magnetic resonance imaging, a software package for a magnetic resonance (MR) imaging system, a software package for upgrading a magnetic resonance (MR) imaging system and a computer program product.
