fMRI for primates at 7T whole body MRI is still a big challenge because no body-coil is provide and the necessary fixation unit does not fit into commercial volume coils. This study shows how the travelling-wave concept can be optimized to work as an efficient body-coil replacement. By simulating the RF-system including the complete 7T whole body scanner it was possible to consider all the important parameters of the experiment. Directional characteristics, distance to the object, and the excitation parameters of the constructed patch antenna were optimized A phased array coil was designed for primate fMRI of macaques.
