Abstract
In a method and an arrangement for magnetic resonance signal transmission, a first channel of a local coil arrangement has a first individual antenna that receives a first magnetic resonance signal, and a first frequency converter connected with the first individual antenna, and the first frequency converter forms a first signal with the first magnetic resonance signal supplied thereto and a first oscillator signal supplied thereto. A second channel of the local coil arrangement has a second individual antenna that receives a second magnetic resonance signal, and a second frequency converter connected with the second individual antenna, and the second frequency converter forms a second signal from the second magnetic resonance signal supplied thereto and a second oscillator signal supplied thereto. The local coil arrangement has a signal combination device that applies the first signal and the second signal to a single transmission path. At least one of the oscillator signals has a frequency that corresponds to the difference between the frequency of a first synthesizer frequency signal and the frequency of a second synthesizer frequency signal that are supplied to the local coil a…
