Abstract:
1. An arrangement for transmission of digital signals in a magnetic resonance apparatus, comprising: a local coil comprising a reception antenna that receives magnetic resonance signals, an amplifier connected to the reception antenna that amplifies the received magnetic resonance signals, and an analog-to-digital converter connected to the amplifier that converts an amplified analog signal from the amplifier into a digital signal emitted at an output of the analog-to-digital converter; a transmission device connected to the output of the analog-to-digital converter that transmits said digital signal into free space by capacitive coupling transmission; a reception device capacitively coupled with said transmission device that receives, via free space, said digital signal from said transmission device; and a transducer connected to said reception device that forms a digital reception signal from the capacitively transmitted signal received by said reception device.
