In a simultaneous MR-PET experiment, an RF resonator for MRI is placed inside the field-of-view of the PET scanner. Attenuation caused by RF coil components can cause severe artefacts in PET images if not adequately corrected. Although it may be possible to minimise subject-specific attenuation and scatter effects, correcting those due to the RF coil is still a challenging task. In this work, we have designed and constructed a number of RF coils constructed utilising a variety of copper conductors and evaluated their characteristics from the MR and PET points of view.
