Arrangement for transfer of magnetic resonance signals
2007
The invention relates to an arrangement for the transmission of magnetic resonance signals with a transmission link (WPA) that connects a local coil (LS) with a receiver (REC1). A first channel (K1) the local coil (LS) has a first individual antenna (LA1) for receiving a first Magnetresonanzsingals (MR1) and a with the first individual antenna (LA1) connected to the first mixer (M1), wherein the first mixer supplied from the first magnetic resonance signal (MR1) an intermediate-frequency first signal (MR1ZF1) forms. A second channel (K2) of the local coil (LS) has a second individual antenna (LA2) for receiving a second magnetic resonance signal (MR2), and a with the second individual antenna (LA2) connected to the second mixer (M2), wherein the second mixer supplied from the second magnetic resonance signal (MR2) an intermediate-second signal (MR2ZF2) forms. The local coil (LS) has a device for signal Summary (DPF) that the intermediate-frequency first signal by means of frequency division multiplexing (MR1ZF1) of the first channel (K1) and the intermediate-second signal (MR2ZF2) of the second channel (K2) summarizes so that it via the transmission link (WPA) to the receiver (REC1) passes. The receiver (REC1) comprises an A / D converter (ADC1, ADC2), on the one of the transmitted intermediate frequency signals (ESZF1, ESZF2) reaches an allocable channel (K1, K2) for with a sampling frequency (FS) for digitizing to be scanned.
