the coupling of RF noise between electronics in the PET system and RF coil of the MRI system can degrade the MR image quality. In addition, the center frequency of the RF coil may experience shifting due to the PET insert. In order to solve the RF noise coupling and frequency shifting problems, an appropriate RF shield should be used. For an MRI-PET fusion system with an add-on/off type PET insert, a gold-mesh tape shield is proposed for the RF coil in this study.
