Abstract:
1. A transmission device for use in a magnetic resonance system having a plurality of local coils, for transmitting magnetic resonance signals from the local coils to an evaluation device, said transmission device comprising: a single circuit board; a plurality of preamplifiers integrated on the circuit board, said preamplifiers respectively having inputs configured to receive magnetic resonance signals from the local coils; a plurality of analog/digital converters integrated on the circuit board respectively having inputs connected to outputs of the preamplifiers; a multiplexer integrated on said circuit board having a plurality of inputs respectively connected to outputs of said analog-digital converters, said multiplexer multiplexing the outputs of the analog/digital converters at a single multiplexer output; an electro-optical transducer having an input connected to the output of the multiplexer, said electro-optical transducer transducing the output of the multiplexer into an optical signal; an optical waveguide connected to an output of the electro-optical transducer that transmits the optical signal to a location remote from the electro-optical transducer and the circuit board; and an opto-electrical transducer connected to the waveguide that converts the optical signal from the waveguide into an electrical output signal, said opto-electrical transducer having an output at which the electrical signal is present configured for connection to the evaluation unit.
