Abstract:
An MRI coil having an inductor and a high temperature superconducting capacitor comprising:a substrate comprising a dielectric and having a surface, an inductor on the surface, and a capacitor comprisinga first superconducting plate member fabricated on the substrate and having a plurality of tines which extend along the surface of the substrate, a second superconducting plate member fabricated on the substrate and having a plurality of tines which extend along the surface of the substrate and are interspersed between the tines of the first plate member; and a tuning capacitor connected in parallel with said capacitor, said tuning capacitor comprisinga substrate comprising a dielectric and having a surface, a first tuning superconducting plate member fabricated on the substrate and having a plurality of tines which extend along the surface of the substrate, a second tuning superconducting plate member fabricated on the substrate and having a plurality of tines which extend along the surface of the substrate and are interspersed between the tines of the first plate member, and a tuning element adjustably positioned adjacent said tuning capacitor.
