The purpose of this study was to develop and evaluate the novel coil designs with new materials adopted to reduce the coil impact on PET image quality. We developed a new plastic-free 3T 16-channel flexible anterior array (AA) RF coil with V0 flammability rating and biocompatibility (PET/MR prototype AA2) for torso and cardiac imaging and validated the PET performances for a GE conventional AA coil and two improved PET/MR prototype coils. The results show a 48% and a 79% average sensitivity loss improvement on PET/MR prototype AA1 coil and PET/MR prototype AA2 coil, respectively, from GE conventional AA coil.
