    摘要： A data rate controlling feedback loop evaluates an actual instantaneous available quality of service of a communication link for transmitting data and controls the data rate based on an evaluation result, Feedback control may both be local to a device for acquiring examination data, such as a magnetic resonance imaging coil, or over the communication link by reducing the data rate at least momentarily to fit the communication link's performance over time, enabling a graceful degradation of an image quality at lower data rates.

    摘要： The present invention relates to a data rate controlling feedback loop (355, 360) that can evaluate an actual instantaneous available quality of service of a communication link (345) for transmitting data and control the data rate based on an evaluation result. Feedback control may both be local to a device for acquiring examination data such as e.g. a magnetic resonance imaging coil or over the communication link by reducing the data rate at least momentarily to fit the communication link's performance over time, enabling a graceful degradation of an image quality at lower data rates.

    摘要： A magnetic resonance system includes a wireless local coil which functions as a transmit only or a transmit and receive coil. The local coil includes an RF coil with a plurality of coil elements. A corresponding number of transmit amplifiers apply RF signals to the RF coil elements to transmit an RF signal. A peak power supply provides electrical power to the transmit amplifiers to transmit relatively high power RF pulses. A trickle charging device recharges the peak power supply between RF pulses front a local coil power supply. A power transfer device wirelessly transfers power to a coil power supply recharging device which recharges the local coil power supply.

A peak power supply (56) provides electrical power to the transmit amplifiers to transmit relatively high power RF pulses. A trickle charging device (66) recharges the peak power supply between RF pulses from a local coil power supply (60). A power transfer device (64) wirelessly transfers power to a coil power supply recharging device (62) which recharges the local coil power supply (60).
