Macaque monkey is a critical model for fMRI to investigate large scale functional network. In this work, an 8 channel loop array with shield birdcage transmit coil is proposed to achieve high resolution homogeneous macaque brain images at 3T MRI. Both phantom and in-vitro experiments demonstrate the capability of the proposed design of achieving homogeneous transmit field and high SNR in the whole brain region, which provides the possibility to perform in-vivo macaque fMRI experiments to investigate large-scale functional network.
