An imaging apparatus that incorporates an RF coil assembly and RF shield as part of a magnetic resonance imaging (MRI) system is disclosed. The imaging apparatus includes an MRI system having a plurality of gradient coils, an RF coil former having inner and outer surfaces, an RF shield positioned on the outer surface of the RF coil former so as to be formed about the RF coil former, and an RF coil positioned on the inner surface of the RF coil former, with the RF coil coupled to a pulse generator to emit an RF pulse sequence and receive resulting MR signals from a subject of interest. The RF coil former comprises a generally cylindrical member having an indented portion indented in a radial direction inwardly from the outer surface, with the RF shield conforming to the RF coil former so as to also have an indented portion. |
