Abstract: A magnetic resonance coil system 18 allows for the use of modular components and which in one embodiment is particularly well-suited for use with small animals and includes an animal receiving apparatus 202, a transmit coil module 204, and a receive coil module 206. The receive coil module 206 includes a cryogenic receive coil. The coil system 18 is selectively insertable in the bore of the gradient coil of a magnetic resonance examination system.

Abstract: A tunable superconductor apparatus or associated method. The apparatus comprises a coil, a first superconductor film portion, a second superconductor film portion, and an actuator. The first superconductor film portion is electrically coupled to the coil. The second superconductor film portion is inductively coupled to the first superconductor film portion. Displacement of the second superconductor film portion relative to the first superconductor film portion changes the capacitance between the second superconductor film portion and the first superconductor film portion. The actuator is capable of relatively displacing the second superconductor film portion and the first superconductor film portion to change a resonant frequency of the tunable superconductor apparatus.
