Abstract: A method for determining communication latency in a magnetic resonance tomography system includes emitting a high-frequency pulse at a first timepoint, receiving the high-frequency pulse by a local coil arrangement of the magnetic resonance tomography system, and transmitting a return signal from the local coil arrangement to a receiving unit. The method also includes receiving the return signal by the receiving unit at a second timepoint, and evaluating a time difference between the first timepoint and the second timepoint in order to determine the communication latency.

Abstract: An arrangement for the transmission of magnetic resonance signals that are received with the aid of local coils is provided. The magnetic resonance signal is fed to an analog/digital converter and digitized by the analog/digital converter. The magnetic resonance signal is compressed in amplitude before being fed to the analog/digital converter, is low-pass filtered or band-pass filtered, and is expanded after digitization by the analog/digital converter. A clock rate that is higher by a factor 2n than a sampling rate n of the analog/digital converter (ADC) is used for the digital expander. A digital equalizing filter for compensating for a filter transmission function in a transition range may also be used.

Abstract: A communication method for communication between a first and a second communication apparatus, where at least one wanted signal is transmitted from the second communication apparatus to the first communication apparatus is provided. The method includes sending a first carrier signal at a first frequency using the first communication apparatus. The method also includes receiving the first carrier signal using the second communication apparatus and generating a second carrier signal at a second frequency. The method includes changing the second frequency and/or a specified phase angle, and/or modulating the second carrier signal in each case as a function of the wanted signal in order to generate a transmit signal. The transmit signal is sent by the second communication apparatus, and the transmit signal is received and demodulated in order to recover the wanted signal using the first communication apparatus.

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.
