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: 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.

Abstract: A transmitter for pilot tone navigation in a magnetic resonance tomography system includes a power supply and an antenna. The transmitter is configured to transmit a pilot tone signal via the antenna. The transmitter also includes a decoupling element in order to protect a transmitter output from signals that the antenna receives with excitation pulses of the magnetic resonance tomography system during a magnetic resonance tomography. In a method, movement-dependent changes to the pilot tone signal of the transmitter are identified by a controller of the magnetic resonance tomography system.

Abstract: A detuning apparatus for a receive coil for a magnetic resonance device includes a number of coil elements. The coil elements may be selectively connected to a receive channel of a data processing apparatus by way of a switching apparatus. Each of the coil elements includes at least one detuning assembly such as, for example, a PIN diode that may be switched between a detuning state and a receive state by way of a continuous switching signal. A controller is provided to switch the switching apparatus and to generate the switching signals. The detuning apparatus has first diplexers connected upstream of the switching apparatus for injecting switching signals for switching the detuning assembly for coil elements to be detuned dynamically. The detuning apparatus also includes detuning modules for each of the coil elements to switch the detuning assembly to the detuning state if there is no switching signal present.
