Abstract: An antenna arrangement for magnetic resonance applications includes antenna elements substantially parallel to a common central axis, distributed around the central axis at a distance from the central axis, and enclosing an essentially cylindrical volume. The antenna arrangement includes intermediate connections that connect to immediately adjacent antenna elements at connection points that lie between the ends of the antenna elements. A preamplifier connects to each of the intermediate connections and has an output that, in a receive mode, corresponds to a respective feed-out point. In send mode, the antenna arrangement injects radio-frequency signals into the antenna elements using the injection points. The antenna arrangement is also configured to adjust the intermediate connections to a higher resistance when the antenna arrangement is in the send mode and at least some of the intermediate connections to a lower resistance when the antenna arrangement is in the receive mode.

Abstract: Front bandpass filters that are essentially transmissive only between a minimum frequency and a maximum frequency filter the magnetic resonance signals. Front frequency mixers mix output signals of each of the bandpass filters with a front LO frequency that is standard for all the magnetic resonance signals. Rear bandpass filters that are essentially transmissive only around a front intermediate frequency filter the output signals of the front frequency mixers. Rear frequency mixers mix output signals of each of the rear bandpass filters with a respective constant rear LO frequency. Frequency filters that are transmissive for frequencies in the range of the difference of the rear LO frequency that is supplied to the rear frequency mixer arranged upstream thereof and the front intermediate frequency filter the output signals of the rear frequency mixers. Output signals of the frequency filters are combined into a common signal, which is transmitted onward.
