Abstract: An arrangement for processing a non-symmetrical signal includes an apparatus configured to balance and filter an image frequency of a nominal frequency of the non-symmetrical receiving signal. The apparatus includes a modified Boucherot bridge having a series or parallel oscillating circuit that replaces inductive or capacitive components of a conventional Boucherot bridge, such that the modified Boucherot bridge is in the harmonized state with the image frequency to be faded out and has a predetermined impedance with the nominal frequency on its symmetrical output terminals. The nominal frequency has a predetermined impedance on its symmetrical output terminals. The nominal frequency is transmitted as a signal balanced to ground to the symmetrical output terminals of the modified Boucherot bridge.

Abstract: An arrangement for transmitting magnetic resonance signals, with a transmission link that connects a local coil with a receiver, has a first channel of the local coil with a first single antenna to acquire a first magnetic resonance signal, as well as a first mixer connected with the first single antenna. The first mixer forms an intermediate-frequency first signal from the supplied first magnetic resonance signal. A second channel of the local coil has a second single antenna to acquire a second magnetic resonance signal, as well as a second mixer connected with the second single antenna. The second mixer forms an intermediate-frequency second signal from the supplied second magnetic resonance signal. The local coil has a device for signal combination that, by frequency multiplexing, that combines the intermediate-frequency first signal of the first channel and the intermediate-frequency second signal of the second channel so that it arrives at the receiver via the transmission path. The receiver has an A/D converter at which one of the transmitted intermediate-frequency signals of an associated channel arrives in order to be sampled with a sampling frequency for digitization. For frequency conversion, a first local oscillator frequency is connected at the first mixer and a second local oscillator frequency is connected at the second mixer. the first and second local oscillator frequencies are selected such that intermediate-frequencies formed by the frequency conversion are mirror-symmetrical relative to the sampling frequency of the A/D converter.

Abstract: A local coil arrangement for magnetic resonance applications has a base body in which at least one local coil is arranged. An excitation signal to excite an examination subject to emit a magnetic resonance signal can be emitted by the local coil and/or a magnetic resonance signal emitted by the examination subject can be received by means of said local coil. At least one volume region is present in the base body, in which an amount of a substance is located that can be excited by means of the coil or another coil so as to emit a magnetic resonance signal. A shielding is arranged in the base body. The shielding can be controlled so as to either shield or not shield the volume region depending on the control state, so that the volume region is occluded or visible with regard to magnetic resonance applications.
