Transmitting and/or receiving MRI signals for a MRI examination

A magnetic resonance imaging (MRI) method configured for transmitting, receiving, or transmitting and receiving MRI excitation signals that are utilized in a MRI examination of an object by a magnetic resonance scanner using an MRI arrangement comprising a superconducting split ring resonator, a cryostat, and a conventional coil, the MRI method comprising:

• receiving a MRI measurement signal in a reception state from the object that is being examined by utilizing the superconducting split ring resonator;
• generating predeterminable ambient conditions in a cavity of the MRI arrangement, wherein the superconducting split ring resonator is located in the cavity;
• and
• transmitting a MRI excitation signal in a transmission state, reading out the MRI measurement signal received by the superconducting split ring resonator, or both transmitting the MRI excitation signal and reading out the MRI measurement signal received by the superconducting split ring resonator, wherein the conventional coil is located outside of the cryostat and wherein the conventional coil is inductively coupled to the superconducting split ring resonator,
• wherein the superconducting split ring resonator is in a non-superconducting state when the superconducting split ring resonator is in the transmission state, and
• wherein the MRI measurement signal induces a signal in the superconducting split ring resonator, when the superconducting split ring resonator is in the reception state, and
• wherein the inductively coupled conventional coil is utilized in order to read out the signal induced in the superconducting split ring resonator by the inductive coupling.

A magnetic resonance scanner comprising:

• a magnetic resonance imaging (MRI) arrangement configured for transmitting, receiving, or transmitting and receiving MRI signals that are utilized in examining an object, the MRI arrangement comprising:
• a superconducting split ring resonator configured to receive a MRI measurement signal from the object being examined, the superconducting split ring resonator comprising at least a first ring-shaped interrupted conductor made of a superconducting material, wherein the first ring-shaped interrupted conductor comprises a first opening and a first taper;
• a cryostat configured to generate predeterminable ambient conditions in a cavity of the MRI arrangement, wherein the superconducting split ring resonator is arranged in the cavity and wherein the generated predeterminable ambient conditions place the first ring-shaped interrupted conductor into a superconducting state, and
• a conventional coil that is configured to transmit an MRI excitation signal and also read out the MRI measurement signal that is received by the superconducting split ring resonator, wherein the conventional coil is located outside of the cryostat and wherein the conventional coil is inductively coupled to the superconducting split ring resonator.
