Abstract: A method for wireless transfer of energy to a local coil system for a magnetic resonance system is provided. The method includes determining an energy requirement value representing a minimum energy level to be fed to the local coil system, so that the local coil system may carry out a predetermined function over a predetermined time period. Energy is transferred adaptively to the local coil system depending on the energy requirement value.

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: In an arrangement for conversion of an analog acquisition signal of an acquisition coil of a magnetic resonance apparatus into a digital signal, the output of the acquisition coil is connected with a low-noise amplifier such that the analog acquisition signal from the acquisition coil arrives at the amplifier. The amplifier is connected at the output side with a device for analog-digital conversion, such that the analog acquisition signal arrives at the device for analog-digital conversion as an amplified acquisition signal for analog-digital conversion. The device for analog-digital conversion is designed as a delta-sigma modulator that forms a digital data stream with a width of one bit from the amplified acquisition signal.

Abstract: A device for recovering a temporal reference in a free-running magnetic resonance tomography (MRT) receive chain includes a time reference encoder and a time reference decoder. The time reference encoder is configured to generate a modulation signal as a function of a reference clock, where the modulation signal is configured for a correlation with a temporal resolution less than a maximum predetermined phase deviation and a maximum that may clearly be identified. The time reference decoder is configured to receive, via the first signal input, a receive signal as a function of the modulation signal, perform a correlation with a reference signal, and generate a signal as a function of a temporal reference of the modulation signal in the receive signal in relation to the reference signal.
