Abstract
The invention relates to a RF reception antenna device () for receiving MR signals in a MR imaging system. The device () comprises a RF resonant circuit including a RF reception antenna () for picking up the MR signals, and a RF amplifier () connected at its input to the RF resonant circuit for amplifying the picked up MR signals. The invention proposes to make provision for a detection circuit () configured to derive a switching signal from an output signal of the RF amplifier (). A switching circuit () is responsive to the switching signal, wherein the switching circuit () is configured to switch the RF resonant circuit between a resonant mode and a non-resonant (i.e. detuned) mode.
