Patent ID: 8489025

Claim:
A method for transmitting at least two magnetic resonance signals that are each detected by a respective local coil, the method comprising: filtering each of the at least two magnetic resonance signals in a front bandpass filter, the at least two magnetic resonance signals having frequencies substantially equal to a Larmor frequency, the front bandpass filters being essentially transmissive only between a minimum frequency and a maximum frequency; mixing, in a respective front frequency mixer, output signals of the front bandpass filters with a respective front local oscillator (LO) frequency that is standard for the at least two magnetic resonance signals, the front LO frequency being set such that a difference between the front LO frequency and the Larmor frequency is approximately equal to a predetermined front intermediate frequency that is greater than the maximum frequency; filtering output signals of the front frequency mixers in a respective rear bandpass filter, the rear bandpass filters being essentially transmissive only around the predetermined front intermediate frequency; mixing, in a respective rear frequency mixer, the output signals of the rear bandpass filters with a respective rear LO frequency, the rear LO frequencies being constant and the amounts of differences between the rear LO frequencies and the predetermined front intermediate frequency being different from one another in pairs; filtering, in a respective frequency filter, the output signals of the rear frequency mixers, the frequency filters being configured such that the frequency filters are transmissive for frequencies in the range of a difference between the rear LO frequency that is supplied to the rear frequency mixer arranged upstream and the front intermediate frequency, and being configured such that the frequency filters are non-transmissive for frequencies in the range of the differences between all other rear LO frequencies and the predetermined front intermediate frequency; and combining the output signals of the frequency filters into a common signal and transmitting the common signal.
