    摘要： The present embodiments relate to a local coil system for a magnetic resonance system. The local coil system includes at least one local coil for detecting MR response signals and at least one transmitting device for the wireless transmission of signals to a receiver of the magnetic resonance system. The local coil system is embodied with a transmitter-side diversity. A receiver-side diversity may exist in the magnetic resonance system.

    摘要： The embodiments relate to an image reconstruction to be carried out on a base unit of a MRI system, where data is formed by reception signals obtained by a local coil unit. Provisions are made for an alternating magnetic field, modulated in accordance with a reference clock, the alternating magnetic field to be used by the local coil unit for obtaining electric energy for supplying local electronics of the local coil unit and the reference clock to be retrieved from the received alternating magnetic field by the local electronics, a radio signal containing MRI information representing the reception signals and clock information representing the retrieved reference clock to be produced by the local electronics and transmitted to the base unit, and the received radio signal to be processed by the base unit such that the data and the clock information are retrieved therefrom and provided for the image reconstruction.

    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 system and method for converting an analog detection signal of a magnetic resonance detection coil into a digital detection signal and for transmitting the detection signal to an evaluating device. In an embodiment, the detection signal is digitized by an analog-to-digital converter, decimated by a decimation filter, transmitted through a transmission route, then equalized by an equalizing filter.
