Resonator for magnetic resonance imaging

摘要

A single turn, asymmetric solenoidal coil for imaging the hand and wrist of a human subject. The asymmetric shape of the coil allows for uniform RF field energy to be distributed along the hand and wrist of the subject. The shape of the coil is maintained by a hollow, elongated member of dielectric material. A complementary pair of foils are attached to the outer surface of the hollow, dielectric member. The foils are separated by axial gaps and electrically coupled to each other by capacitors disposed along the length of each gap.
