The construction of a parallel phased array MR brain coil that is compatible with the state of the art simultaneous MR-PET Brain scanners requires unique material and design specifications. In this study, we evaluate the design criteria of a 32-channel MR-PET coil (including conductor materials, cable thicknesses and component placements with experiment and simulation) to improve SNR and parallel imaging of MR while minimizing the interference with 511 keV γ-ray detection from the PET camera.
