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.
