FIELD: physics.
SUBSTANCE: invention relates to the field of magnetic resonance imaging (MRI). Radio frequency (RF) receiving coil device for use in a magnetic resonance (MR) imaging system comprises an RF receiving coil, a plug for connecting the RF receiving coil with an MR imaging system, a sensor for sensing the presence of a magnetic field of the MR imaging system, a detector for detecting whether a plug is connected to the MR imaging system, and a warning means for generating an warning signal when the sensor senses the presence of the magnetic field of the MR imaging system and the detector detects that the plug is not connected to the MR imaging system.
EFFECT: increase in safety for the researched subject during the use of the MR imaging system.
