摘要： An arrangement includes a superconducting split ring resonator, a cryostat, and a copper coil. The resonator is arranged in the cryostat and includes at least one ring-shaped conductor made of a superconducting material and including an opening and a taper. The copper coil may be used to transmit a MRI excitation signal. This signal causes a current to be induced in the conductor that leads to the breakdown of the superconductivity. The conductor is detuned and therefore no longer develops an interfering effect. It is possible for the effect of the breakdown of superconductivity to be used for detuning in a targeted manner. After the transmission is complete, the conductor returns into the superconducting state and acts as a superconducting reception antenna for the MRI measurement signal. The copper coil is inductively coupled to the conductor and configured to read out the signal induced in the conductor.

摘要翻译： 一种装置包括超导分裂环谐振器，低温恒温器和铜线圈。 谐振器布置在低温恒温器中，并且包括由超导材料制成并且包括开口和锥形的至少一个环形导体。 铜线圈可用于传输MRI激励信号。 该信号导致导体中导致的电流导致超导性的破坏。 导体失谐，因此不再产生干扰效应。 有可能以有目的的方式将超导性破坏的效果用于失谐。 传输完成后，导体返回超导状态，作为MRI测量信号的超导接收天线。 铜线圈感应耦合到导体并且被配置为读出在导体中感应的信号。
