ABSTRACT:
In a method for processing radio frequency signals of a magnetic resonance imaging system in which the coil portion of the magnetic resonance imaging system includes a body coil and a local coil, radio frequency signals are supplied to the body coil, and these radio frequency signals are coupled to said local coil, and transmitted by said local coil into a region to be examined. A corresponding radio frequency system has a local coil and a body coil, with power coupling between the local coil and the body coil; during the phase for transmitting the radio frequency signals. The body coil serves to couple the radio frequency signals to be transmitted to the local coil, and the local coil serves to transmit the coupled radio frequency signals to a region to be examined. This method and system allow the transmitting function of the local coil to be achieved without having a coil plug on a patient bed to provide a radio frequency signal transmitting channel.
