    摘要： 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.

    摘要： A method for the detection of an object by the TDOA principle is provided. The object transmits a signal, which is received by a plurality of stations having known positions. The stations' clocks can have different unknown time delays in relation to each other. An additional stationary reference station having a known position relative to the stations and transmitting a signal that is received by the stations is provided. An unknown transmission delay can be generated between the emission of the signal from the object and the emission of the signal from the reference station. For each station the difference in travel time between receipt of the signal from the object and the signal from the reference station and the difference of the travel time differences between the stations are determined. Mathematical algorithms for determining the location are performed.
