Abstract
An imaging apparatus is disclosed that includes an MRI system, either as a stand-alone system or hybrid PET-MRI system. The MRI system includes gradient coils positioned about a patient bore, an RF coil former comprising an inner surface and an outer surface, 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 and about the patient bore, 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 shield includes a plurality of slits formed therein configured to disrupt the formation of gradient field induced eddy currents on the RF shield, so as to prevent the generation of high temperature profiles on the surface of the shield.
