摘要： In a magnetic resonance tomography local coil arrangement and a method for processing signals received thereby, at least one local coil is fashioned to receive at least one reception signal and at least one amplifier is provided that amplifies the at least one reception signal. A frequency converter generates at least one intermediate frequency signal from the at least one reception signal the intermediate frequency of the intermediate frequency signal differing from the reception signal frequency of each reception signal. An analog-digital converter converts the analog intermediate frequency signal into a digitized signal. A shielding device shields against at least radio-frequency signals, the shielding device surrounding at least the analog-digital converter. At least one frequency filter is arranged between the at least one local coil and the analog-digital converter, the frequency filter exhibiting a transmission range for signals with the intermediate frequency of an intermediate frequency signal. The digitized signal is transmitted from the local coil arrangement.

摘要： 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.

摘要： An arrangement to transmit magnetic resonance signals has at least two reception branches. Each reception branch contains a single antenna of a local coil as well as an amplifier connected with the single antenna, such that an amplified magnetic resonance signal is formed from a magnetic resonance signal that is acquired via the single antenna. In a multiplexer, each input is connected with a respective reception branch, such that the amplified magnetic resonance signals of the reception branch are combined by the multiplexer into a resulting signal using a time multiplexing method. A transmission path is connected on one side with an output of the multiplexer and on the other side with a receiver, such that the resulting signal is transmitted from the multiplexer to the receiver via the transmission path.
