Patent ID: 8055196

Claim:
An arrangement for transmitting magnetic resonance signals comprising: a local coil configured to receive analog magnetic resonance signals; a receiver configured to convert said analog magnetic resonance signals into digital signals; a transmission link placing said local coil in communication with said receiver to transmit said analog magnetic resonance signals to said receiver; said local coil comprising a first channel comprising a first single antenna that acquires a first analog magnetic resonance signal, and a first mixer connected to said first single antenna, said first mixer being configured to form an intermediate-frequency first analog signal from said first analog magnetic resonance signal; said local coil comprising a second channel comprising a second single antenna configured to receive a second analog magnetic resonance signal, and a second mixer connected to said second single antenna, said second mixer forming an intermediate frequency second analog signal from said second analog magnetic resonance signal; said local coil comprising a signal combiner configured to combine said intermediate frequency first analog signal of said first channel and said intermediate frequency second analog signal of said second channel by frequency multiplexing to produce said analog magnetic resonance signal that is communicated via said transmission link to said receiver; said receiver comprising an analog-to-digital converter that samples the transmitted intermediate frequency signals with a sampling frequency to produce said digital signal; for frequency conversion into a first intermediate frequency range, said first mixer being supplied with a first local oscillator signal, and for frequency conversion into a second intermediate frequency range, said second mixer being supplied with a second local oscillator frequency; and said first and second local oscillator frequency respectively causing the respective intermediate frequencies formed by the frequency conversion in the first and second mixers to be mirror symmetric relative to said sampling frequency of said analog-to-digital converter.
